Expert Insulation Services in North Texas
Blown-in attic insulation, spray foam, wall cavity insulation, and rigid foam board installation. MartinBuilt LLC helps North Texas homeowners lower energy bills, improve comfort, and protect their homes — year round.
North Texas Insulation Contractor You Can Trust
In the extreme Texas climate — where summer highs top 100°F and winter cold snaps can plunge below freezing — proper insulation isn\'t a luxury, it\'s a necessity. Inadequate insulation forces your HVAC system to work overtime, driving up energy bills and shortening equipment life. MartinBuilt LLC provides comprehensive insulation services for attics, walls, crawl spaces, and foundations using blown-in cellulose, fiberglass, open-cell and closed-cell spray foam, and rigid foam board (XPS and EPS).
Based in Watauga, TX, we serve residential and light commercial customers throughout Tarrant County, Dallas County, Denton County, and Collin County. Whether you\'re upgrading an older home, insulating new construction, or addressing energy efficiency issues, our crew delivers professional results backed by a licensed general contractor\'s guarantee.
Blown-In Attic Insulation
Blown-in insulation is one of the most effective and cost-efficient ways to insulate your attic. Using high-performance cellulose or fiberglass loose-fill, we blanket your attic floor with a seamless thermal barrier that fills every gap, crack, and crevice — areas that batt insulation often misses. Blown-in insulation is ideal for North Texas homes where summer attic temperatures can exceed 150°F, drastically reducing cooling costs and improving whole-home comfort.
- Cellulose & fiberglass loose-fill options
- R-30 to R-60 coverage for maximum efficiency
- Fills gaps around wiring, pipes & ductwork
- Ideal for existing homes & new construction
- Quick installation — most attics done in one day
- Helps reduce energy bills up to 30–50%
Spray Foam Insulation
Spray polyurethane foam (SPF) insulation provides the highest R-value per inch of any insulation material, creating a continuous air barrier that dramatically reduces energy loss. We install both open-cell and closed-cell spray foam for attics, crawl spaces, rim joists, and walls. Closed-cell foam also acts as a moisture and vapor barrier — critical for North Texas humidity. Open-cell foam is lighter and more flexible, perfect for interior walls and sound dampening.
- Open-cell foam — R-3.7 per inch, excellent sound barrier
- Closed-cell foam — R-6.5 per inch, moisture resistant
- Creates seamless air barrier (no gaps or seams)
- Ideal for attic roof decks, crawl spaces & rim joists
- Strengthens building structure (closed-cell)
- Reduces HVAC strain and extends equipment life
Wall Cavity Insulation
Properly insulated walls are essential for maintaining consistent indoor temperatures and reducing energy waste. We offer blown-in dense-pack cellulose, fiberglass batts, and injection foam for new construction and existing wall cavities. For retrofit projects, we can inject insulation through small holes — minimizing disruption to your drywall and exterior finish. Our wall insulation services are ideal for older North Texas homes that were built with little or no insulation.
- Dense-pack cellulose for existing walls
- Fiberglass batt installation for new builds
- Injection foam for retrofit without removing drywall
- Reduces drafts and cold spots throughout your home
- Improves soundproofing between rooms
- Works with all exterior finishes — brick, siding, stone
Rigid Foam Board — XPS & EPS
Extruded polystyrene (XPS) and expanded polystyrene (EPS) rigid foam boards deliver continuous insulation for foundations, exterior walls, and under-slab applications. XPS offers higher moisture resistance and compressive strength, making it ideal for below-grade and high-moisture areas. EPS provides excellent thermal performance at a lower cost, perfect for above-grade sheathing and ICF (insulated concrete form) construction. MartinBuilt installs both types to match your project's specific requirements.
- XPS — R-5 per inch, high moisture resistance
- EPS — R-3.6 to R-4.2 per inch, cost-effective
- Foundation & below-grade waterproofing insulation
- Exterior continuous insulation (CI) for code compliance
- Under-slab insulation for radiant floor systems
- Compatible with ICF and SIP construction methods
Benefits of Professional Insulation
Investing in quality insulation delivers immediate and long-term returns for your home, comfort, and wallet.
Lower Energy Bills
Proper insulation can reduce heating and cooling costs by 30–50%, paying for itself within 2–5 years in most North Texas homes.
Year-Round Comfort
Eliminate hot spots, cold drafts, and temperature swings. Enjoy consistent comfort in every room, every season.
Noise Reduction
Insulation dampens outside noise and reduces sound transfer between rooms — creating a quieter, more peaceful home.
Energy Efficiency & Sustainability
Reduce your carbon footprint and energy consumption. Many insulation materials use recycled content and are GREENGUARD certified.
HVAC System Protection
Less strain on your heating and cooling equipment means fewer repairs, lower maintenance costs, and a longer system lifespan.
Moisture & Mold Prevention
Spray foam and rigid foam create moisture barriers that prevent condensation, mold growth, and structural damage.
Insulation FAQ
Common questions about insulation services in North Texas.
What type of insulation is best for my attic in North Texas?
For most North Texas homes, blown-in cellulose or fiberglass at R-38 to R-60 provides the best balance of cost and performance. If you have HVAC equipment in the attic, spray foam on the roof deck creates a conditioned attic that protects your ductwork and equipment from extreme heat.
What is the difference between open-cell and closed-cell spray foam?
Open-cell foam (R-3.7/inch) is lighter, more flexible, and excellent for sound dampening. Closed-cell foam (R-6.5/inch) is denser, provides a moisture/vapor barrier, and adds structural rigidity. We recommend closed-cell for exterior walls, crawl spaces, and areas exposed to moisture, and open-cell for interior walls and attic applications.
What is the difference between XPS and EPS rigid foam insulation?
Extruded polystyrene (XPS) has a higher R-value per inch (R-5) and superior moisture resistance, making it ideal for below-grade and foundation applications. Expanded polystyrene (EPS) is more cost-effective (R-3.6 to R-4.2/inch) and is commonly used for above-grade wall sheathing and ICF construction. Both provide continuous insulation that eliminates thermal bridging.
Can you insulate my existing walls without removing drywall?
Yes. We use injection foam and dense-pack cellulose to insulate existing wall cavities through small holes that are easily patched and repainted. This is the most cost-effective way to insulate older homes that were built with minimal or no wall insulation.
How long does insulation installation take?
Most residential blown-in attic jobs are completed in a single day. Spray foam projects typically take 1–2 days depending on scope. Full-home insulation upgrades (attic, walls, and crawl space) usually take 2–3 days.
Do you offer free insulation estimates?
Absolutely. We provide free, no-obligation on-site assessments where we inspect your current insulation, identify problem areas, and recommend the most effective solutions for your home and budget.
