Insulation in Morgan Hill, CA
Crawl space encapsulation and vapor barrier work in Morgan Hill typically runs $3,800-$7,500 for a full encapsulation, with most jobs completed in two days. The combination of 1985-2005 tract housing built to minimum code and the valley’s aggressive wind-driven infiltration means Morgan Hill crawl spaces chronically underperform without proper sealing and moisture control. Call (669) 280-8103 for a written price before any work starts.
Why Morgan Hill Homes Are Different
Morgan Hill sits at the southern throat of Coyote Valley, where afternoon winds funnel aggressively through the gap between the Diablo Range and Santa Cruz Mountains - a microclimatic wind corridor measurably stronger than neighboring Gilroy or San Jose. This means air infiltration through building envelopes is a far greater energy loss driver here than in most surrounding cities, and insulation installed without simultaneous air sealing chronically underperforms, a pattern local contractors encounter repeatedly that simply does not apply to the flatter, more sheltered Bay Area markets to the north.
The rapid suburban buildout from roughly 1985-2005 left large tracts of homes - particularly around East Main Avenue, Dunne Avenue, and master-planned communities like Cochrane - with minimum-code batt insulation, vaulted and cathedral ceilings common to that era’s designs, and little to no attention to air sealing. All of this now significantly undershoots current Title 24 requirements for CEC Climate Zone 4. The valley’s inland position delivers summer highs routinely in the low-to-mid 90s°F alongside cold overnight drops into the 30s°F in winter - a diurnal and seasonal swing larger than coastal Silicon Valley cities - meaning Morgan Hill homes carry both meaningful cooling loads and genuine heating loads that undersized or degraded insulation fails to address on both ends.
Our Main Morgan Hill Services
Most Morgan Hill homeowners who call us start with attic work or spray foam, though blown-in remains popular for retrofits in the older Cochrane and East Main tracts.
Attic Insulation in Morgan Hill
The 1990s cathedral ceilings throughout Coyote Creek and South Morgan Hill developments are a persistent problem: two-by-six rafters leaving only R-19 cavity with no ventilation baffle room, made worse by the valley’s high-wind infiltration. We treat these with dense-pack or spray foam after full air sealing, never batt-over. Every attic job includes a blower-door test - a pressurization reading that shows, in one number, how much air your building envelope was losing before and after. Attic Insulation in Morgan Hill covers our full process and pricing.
Spray Foam Insulation in Morgan Hill
Open-cell and closed-cell foam retrofits are in high demand for Morgan Hill’s thin cathedral ceiling assemblies and unvented crawl spaces where standard materials cannot solve the combined air-leakage and thermal problem. We source from Owens Corning, Johns Manville, and Icynene with no proprietary lock-in, and we seal first, then insulate - in that order. Before-and-after blower-door numbers are published on every applicable job. Spray Foam Insulation in Morgan Hill details R-values and cost ranges.
Blown-In Insulation in Morgan Hill
Blown-in cellulose and fiberglass remain cost-effective for accessible attics in the 1980s and 1990s tracts, but only after the attic floor is fully sealed - top plates, can lights, penetrations, and the hatch. We use GreenFiber and Knauf materials, and we document every step with photos you receive at job close. Blown-In Insulation in Morgan Hill explains when it fits and when spray foam is the better tool.

Crawl Space Encapsulation & Vapor Barrier in Morgan Hill
Crawl space encapsulation and vapor barrier work in Morgan Hill addresses a specific regional problem: the 1985-2005 tract homes built on grade with vented crawl spaces that pull moisture and unconditioned air straight through the floor assembly, compounded by the valley’s wind pressure forcing air through every gap. Crawl Space Encapsulation & Vapor Barrier is our most-called service in the East Main and Dunne Avenue corridors for this reason. The clay-heavy soils and winter temperature swings here mean vapor drive from below is constant, and minimum-code fiberglass batts stapled to joists simply trap moisture against wood.
Crawl Space Vapor Barrier
Signs you need it
Your crawl space has standing water after rain, white mineral deposits on the foundation wall, or a persistent musty smell rising through floor registers.
What it costs in Morgan Hill
A 6-mil to 20-mil vapor barrier installed over bare earth typically runs $1,200-$2,800 depending on crawl square footage and pier count.
How we do it
We rake and level the earth, seam-seal polyethylene sheeting at all overlaps, mechanically fasten at walls and piers, and deliver a Documented Photo Record of full coverage before closing.
Crawl Space Encapsulation
Signs you need it
Your HVAC ducts sweat in summer, hardwood floors cup at the edges, or your energy bills spike despite recent attic work.
What it costs in Morgan Hill
Full encapsulation with sealed vapor barrier, rigid foam wall insulation, and conditioned-air supply typically runs $3,800-$7,500.
How we do it
We seal all vents, install multi-layer vapor barrier with sealed seams, apply rigid foam to foundation walls, and add a dehumidistat-controlled vent or small supply duct to maintain positive pressure.
What Crawl Space Encapsulation & Vapor Barrier Costs in Morgan Hill
| Item | Typical range in Morgan Hill |
|---|---|
| Vapor barrier only (6-20 mil) | $1,200 - $2,800 |
| Full encapsulation with wall insulation | $3,800 - $7,500 |
| Encapsulation + dehumidifier install | $5,200 - $9,000 |
How long does crawl space encapsulation take in Morgan Hill?
Most vapor barrier jobs finish in one day; full encapsulation with wall foam and conditioning takes two to three days. We provide a written scope with day-by-day crew schedule before anyone arrives.
Will encapsulation fix my musty smell?
Yes, if the source is ground moisture and vented crawl air - the two problems encapsulation is designed to eliminate. Call (669) 280-8103 for a free inspection and written price.
Radiant Barrier Installation in Morgan Hill
Radiant barrier installation in Morgan Hill targets a specific climate load: summer attic temperatures in the 140-160°F range driven by the inland valley’s intense solar gain, which then radiates downward through poorly insulated ceiling assemblies. The 1985-2005 tracts with R-19 or R-30 attic insulation and no radiant barrier are particularly vulnerable, as are the cathedral-ceiling homes where insulation depth is physically limited. Radiant Barrier Installation becomes a cost-effective retrofit when attic temperatures are the dominant driver of cooling load.
Attic Radiant Barrier
Signs you need it
Your upstairs rooms stay hot past 10 PM, your AC runs continuously on summer afternoons, or your roof decking is visible and uncoated from inside the attic.
What it costs in Morgan Hill
Attic radiant barrier foil stapled to rafters or laid over existing insulation typically runs $1,100-$2,400 for homes under 2,500 square feet.
How we do it
We install perforated foil across rafter bays or draped over insulation, maintaining ventilation pathways and documenting with photos; we never compress existing insulation.
Radiant Barrier Roof Deck
Signs you need it
You’re re-roofing soon, your current shingles are failing, or you want the most effective radiant barrier assembly without attic access limitations.
What it costs in Morgan Hill
Radiant barrier sheathing or spray-applied coating during re-roof typically adds $1,800-$3,500 to the roofing scope.
How we do it
We coordinate with your roofer to install foil-faced OSB or spray a low-emissivity coating directly to the deck, then verify with infrared imaging at completion.
What Radiant Barrier Installation Costs in Morgan Hill
| Item | Typical range in Morgan Hill |
|---|---|
| Attic foil (rafter or over-insulation) | $1,100 - $2,400 |
| Radiant barrier roof deck (re-roof add-on) | $1,800 - $3,500 |
| Foil + attic air sealing package | $2,400 - $4,200 |
Does radiant barrier work with existing insulation?
Yes - it complements rather than replaces insulation, reducing radiant heat gain so your existing R-value performs closer to its rated value. Call (669) 280-8103 for a free estimate.
How much will my cooling bill drop?
Most Morgan Hill homeowners see 5-15% summer cooling reduction, with the greatest impact in homes with dark shingles and minimal existing attic insulation.
Insulation Removal & Replacement in Morgan Hill
Insulation removal and replacement in Morgan Hill is most often needed in the 1985-2005 tracts where fiberglass batts have compressed, been disturbed by rodents, or absorbed moisture from roof leaks and crawl space vapor drive. The valley’s large temperature swings accelerate thermal breakdown, and the wind corridor pulls fine particles through compromised vapor barriers. Insulation Removal & Replacement is not a standalone service for us - it is always paired with air sealing and a blower-door test to ensure the new material performs.
Contaminated Insulation Removal
Signs you need it
Your attic insulation is stained brown or black, smells of mildew or animal waste, or you’ve had a roof leak that soaked the material.
What it costs in Morgan Hill
Contaminated insulation removal and disposal typically runs $1,500-$3,200 depending on attic square footage and contamination depth.
How we do it
We use HEPA-contained vacuums, bag and seal all material, treat exposed decking with antimicrobial where needed, and deliver photos of clean substrate before new insulation goes in.
Insulation Replacement
Signs you need it
Your insulation is compressed below its original thickness, has visible gaps at eaves and top plates, or was installed before 1990 and never upgraded.
What it costs in Morgan Hill
Full removal and replacement with new blown-in or batt insulation typically runs $2,800-$5,500 for attics under 1,500 square feet.
How we do it
We remove old material, seal all attic floor penetrations and top plates, then install new insulation to current Title 24 depth with a blower-door test to verify.
What Insulation Removal & Replacement Costs in Morgan Hill
| Item | Typical range in Morgan Hill |
|---|---|
| Contaminated insulation removal | $1,500 - $3,200 |
| Full removal + replacement (blown-in) | $2,800 - $5,500 |
| Removal + spray foam replacement | $4,500 - $8,500 |
Can you remove insulation with asbestos?
No - we stop work and refer you to a licensed abatement contractor if we suspect asbestos-containing vermiculite or pre-1980 materials; we do not handle hazardous material removal.
Do I have to leave during removal?
Usually not - our HEPA-contained process keeps living spaces isolated, though we recommend pets and sensitive individuals leave for the day. Call (669) 280-8103 to schedule.
Attic Air Sealing in Morgan Hill
Attic air sealing in Morgan Hill is the single most impactful envelope upgrade for this specific climate, because the Coyote Valley wind corridor forces unconditioned air through every gap in the ceiling plane at rates far exceeding flatter, more sheltered Bay Area markets. The 1985-2005 tracts are particularly leaky: top plates rarely sealed, can lights unbaffled, duct boots pulling attic air directly into HVAC returns. Attic Air Sealing is always our first step before adding insulation, and we publish before-and-after blower-door numbers on every job.
Top Plate & Penetration Sealing
Signs you need it
You feel drafts at interior wall tops in winter, your blower-door test shows excessive leakage at the ceiling plane, or your attic insulation is blackened at the edges.
What it costs in Morgan Hill
Top plate and penetration sealing for a typical 2,000-square-foot home runs $1,400-$2,600.
How we do it
We access top plates by moving insulation aside, seal all gaps with foam and caulk, replace insulation without compression, and photograph every sealed location for your record.
Can Light & Duct Boot Sealing
Signs you need it
Your can lights flicker in wind, your HVAC filter dirties unusually fast, or rooms farthest from the air handler never reach set temperature.
What it costs in Morgan Hill
Sealing can lights with proper covers and duct boots with mastic and metal tape typically adds $800-$1,800 to the air sealing scope.
How we do it
We install fire-rated covers over can lights, seal duct boots with mastic and reinforced tape, and verify with blower-door subtraction testing to quantify the improvement.
What Attic Air Sealing Costs in Morgan Hill
| Item | Typical range in Morgan Hill |
|---|---|
| Top plate & penetration sealing | $1,400 - $2,600 |
| Can light & duct boot sealing | $800 - $1,800 |
| Full attic air sealing package | $2,200 - $4,200 |
How much does air sealing reduce my bills?
Most Morgan Hill homes see 10-25% heating and cooling reduction after proper attic air sealing, with the biggest gains in pre-2000 construction. Call (669) 280-8103 for a blower-door test and written price.
Can you seal without adding insulation?
Yes - air sealing is a standalone service, though we typically recommend addressing both since disturbed insulation rarely goes back down performing at its original R-value.
Wall Insulation in Morgan Hill
Wall insulation in Morgan Hill addresses a gap common to the 1985-2005 tracts: two-by-four exterior walls with R-13 batt insulation that has settled, compressed, or never filled cavities fully, particularly at headers and around electrical boxes. The valley’s wind infiltration makes these thermal bypasses far more consequential than in sheltered coastal markets. Wall Insulation retrofits are most cost-effective when combined with air sealing and targeted to the worst-performing walls identified by infrared imaging.
Drill & Fill Wall Insulation
Signs you need it
Your exterior walls are cold to the touch in winter, you have visible settling gaps at outlets, or your home was built 1985-2005 with no exterior foam sheathing.
What it costs in Morgan Hill
Drill-and-fill dense-pack cellulose for a typical single-story home runs $2,200-$4,500 depending on wall linear footage and cavity condition.
How we do it
We drill 2-inch holes at stud bay intervals, dense-pack cellulose to 3.5 pounds per cubic foot, plug with matching siding or interior patch, and photograph every filled bay.
Injection Foam Wall Insulation
Signs you need it
You have finished walls you don’t want to open, existing insulation is minimal or absent, or you’ve already addressed the attic and still have comfort complaints.
What it costs in Morgan Hill
Injection foam for completed wall cavities typically runs $3,500-$6,500 for a 2,000-square-foot home with full perimeter walls.
How we do it
We access cavities through exterior mortar joints or interior drywall, inject slow-rise foam that fills without bowing studs, trim and patch access points, and verify fill with thermal imaging.
What Wall Insulation Costs in Morgan Hill
| Item | Typical range in Morgan Hill |
|---|---|
| Drill & fill dense-pack cellulose | $2,200 - $4,500 |
| Injection foam (completed walls) | $3,500 - $6,500 |
| Exterior wall + attic package | $5,500 - $10,500 |
Will drill-and-fill damage my siding?
We match plug patches to existing siding or stucco; on wood lap siding we remove and replace full boards where needed for clean results. Call (669) 280-8103 for a free inspection.
Can you insulate walls from inside?
Yes - injection foam and certain dense-pack approaches work from interior drywall with minimal patchwork, ideal for homes with recent exterior paint or stucco.
Attic Cleaning & Rodent Proofing in Morgan Hill
Attic cleaning and rodent proofing in Morgan Hill is frequently needed in the mature suburban tracts where roof rats and mice have established pathways through overhanging oaks and oleander hedges common to the area’s 1990s landscaping. The 1985-2005 homes with unsealed attic vents, deteriorated fascia, and minimal rodent barriers at roof-wall junctions provide easy entry. Attic Cleaning & Rodent Proofing is always paired with air sealing - we seal entry points before cleaning, not after, so the problem stays solved.
Rodent Proofing & Exclusion
Signs you need it
You hear scratching at dusk or dawn, find droppings in the attic or insulation, or see gnaw marks on fascia boards or vent screens.
What it costs in Morgan Hill
Rodent proofing with exclusion work, vent screening, and gap sealing typically runs $1,200-$2,800 for a single-family home.
How we do it
We inspect every roof and wall penetration, install metal flashing and hardware cloth at entry points, seal gaps with rodent-proof materials, and document every location with photos.
Attic Sanitizing & Decontamination
Signs you need it
Your attic smells of urine or decay, insulation is visibly soiled, or you’ve had active rodents for more than one season without cleanup.
What it costs in Morgan Hill
Attic sanitizing and decontamination after rodent removal typically runs $1,800-$3,500 depending on contamination area and insulation involvement.
How we do it
We remove soiled insulation, HEPA-vacuum all surfaces, apply enzymatic sanitizer to break down organic material, and deliver photos of clean substrate before any new work begins.
What Attic Cleaning & Rodent Proofing Costs in Morgan Hill
| Item | Typical range in Morgan Hill |
|---|---|
| Rodent proofing & exclusion | $1,200 - $2,800 |
| Attic sanitizing & decontamination | $1,800 - $3,500 |
| Full cleanup + re-insulation | $3,500 - $7,000 |
How do I know rodents are gone before you seal?
We set monitoring traps, verify no activity for a minimum period, then seal - never seal active animals inside. Call (669) 280-8103 for inspection and written scope.
Is decontamination safe for my family?
Yes - we use non-toxic enzymatic cleaners, keep living spaces isolated during work, and ventilate thoroughly before you re-enter the home.
Home Energy Audit in Morgan Hill
A home energy audit in Morgan Hill provides the documentation that every other service on this page depends on: a blower-door test - a pressurization reading that shows, in one number, how much air your building envelope is losing - plus thermal imaging and insulation inspection to identify where that air is going. The valley’s wind-driven infiltration makes the blower-door result particularly diagnostic here; a leaky Morgan Hill home will test dramatically worse than a similarly built home in sheltered San Jose. Home Energy Audit is the starting point for every major envelope project we undertake.
Blower Door Test
Signs you need it
Your energy bills are rising without rate increases, rooms have persistent temperature differences, or you’re planning insulation work and want a baseline.
What it costs in Morgan Hill
A standalone blower-door test with written report typically runs $350-$550; it is credited toward any follow-up work we perform.
How we do it
We install a calibrated fan in an exterior door, depressurize to 50 Pascals, measure CFM50 leakage, and identify dominant leakage paths with smoke pencils and infrared.
Thermal Imaging Inspection
Signs you need it
You have mystery cold spots, suspect missing insulation behind drywall, or want to verify recent contractor work before final payment.
What it costs in Morgan Hill
Thermal imaging as part of a full audit typically adds $200-$400 to the blower-door scope, or $450-$750 standalone.
How we do it
We scan interior and exterior surfaces with a calibrated infrared camera during controlled temperature differential, mark anomalies on photos, and deliver a report with prioritized repair recommendations.
What Home Energy Audit Costs in Morgan Hill
| Item | Typical range in Morgan Hill |
|---|---|
| Blower-door test with report | $350 - $550 |
| Full audit (blower door + thermal + insulation) | $550 - $850 |
| Audit credited to follow-up work | $0 - $550 |
How long does an energy audit take?
Most audits take two to three hours on-site, with the written report delivered within 48 hours including blower-door readings, thermal images, and prioritized scope. Call (669) 280-8103 to schedule.
Will the audit tell me what to fix first?
Yes - we rank recommendations by cost-effectiveness and your stated priorities, with line-item pricing for each so you can phase work if needed.
