United Home Services in Baltimore: Insulation Installation with Free In-Home Assessment
United Home Services is a licensed insulation contractor serving Baltimore and surrounding counties, specializing in attic, wall cavity, and basement insulation for both single-family homes and small commercial properties.
What United Home Services actually is
United Home Services operates as a regional insulation installer, not a general contractor or energy audit firm. The company holds Maryland Home Improvement License 116095 and focuses on blown-in cellulose, fiberglass, and spray foam applications rather than rigid board or vapor barriers. Work is typically completed by in-house crews rather than subcontractors, which affects both timeline and accountability on site.
Services and pricing
Standard pricing tiers run as follows:
Attic insulation in a 1,500-square-foot home typically costs $1,200 to $2,100 depending on desired R-value (R-38 to R-60) and material choice. Blown-in cellulose averages $0.65 to $0.85 per square foot; fiberglass runs $0.55 to $0.75 per square foot. Spray foam costs more, generally $1.50 to $2.50 per square foot, but requires no air sealing work beforehand.
Basement rim joist and band board sealing with closed-cell spray foam ranges from $800 to $1,600 for a standard Baltimore rowhouse perimeter. Wall cavity injection (for existing homes without access) costs $1,400 to $3,000 depending on linear feet and obstruction severity.
The company offers a free in-home assessment that includes a thermal imaging scan to locate air leaks and a load calculation that recommends specific R-values based on Baltimore's climate zone (4A). This assessment takes 30 to 45 minutes and carries no obligation. Estimates are typically provided within two business days.
Most work does not require permits in Baltimore for residential attic insulation, though basement work may trigger a separate mechanical inspection depending on scope. United Home Services handles permit applications for jobs that require them.
How it compares to other Baltimore insulation options
Insulation supply retailers like Lowe's and Home Depot sell DIY material and referrals to contractors but do not employ dedicated crews; quality varies widely among their network installers and warranties are often material-only.
Mid-Atlantic Insulation, another licensed Baltimore contractor, emphasizes energy audits and rebate coordination with BGE (Baltimore Gas and Electric). Their pricing runs 5 to 10 percent higher for comparable attic work, but they include a blower-door test (a $400 to $600 add-on elsewhere) as part of their baseline service. Choose Mid-Atlantic if you want detailed pre- and post-installation diagnostics; choose United Home Services if you want faster turnaround and lower entry cost for straightforward attic jobs.
Local HVAC companies like Comfort Systems offer insulation as an ancillary service to ductwork sealing but prioritize their core HVAC business. Response times are longer, and pricing is often bundled in ways that obscure per-square-foot cost. Comparison shopping with a dedicated insulation contractor is worthwhile if insulation is your primary need.
Who it suits and who it does not suit
United Home Services is a fit for:
- Homeowners seeking attic insulation upgrades in advance of selling (the most common job in Baltimore's market)
- Properties with clear attic access and no major framing issues
- Budgets under $3,000 for a single-room or attic project
- Those who prefer a single contractor to manage scope and warranty
Not a fit for:
- Homes requiring extensive air-sealing before insulation (the company can do it, but costs escalate significantly)
- Commercial buildings or multi-unit properties (outside their typical scope)
- Customers prioritizing detailed energy modeling before work begins
What the first visit involves
Schedule the free assessment by phone or online form; office staff typically reply within 24 hours. A technician arrives with thermal imaging equipment and a tape measure. They walk the attic (if accessible without obstruction), identify joist spacing, check for existing insulation type and depth, and note any moisture, pest damage, or active vents that might affect application. The technician visually scans for air leaks around electrical penetrations, duct chases, and rim joists.
You receive a one-page estimate stating square footage, recommended R-value, material type, labor cost, and total price. Warranty details (typically 10 years on labor, lifetime on material) are printed on the estimate. Installation typically occurs within two to four weeks of approval, depending on season; spring and fall slots fill faster.
Hours, parking, and logistics
United Home Services operates Monday through Friday, 7 a.m. to 4 p.m., with voicemail available outside business hours. The office is located near Towson and serves all of Baltimore City and Baltimore, Howard, and Anne Arundel counties. No parking is required for the assessment visit; the technician drives directly to the home. Installation crews typically arrive early morning and complete attic jobs within one business day. The property should have clear attic access and temperatures above 40 degrees Fahrenheit for spray foam application. Confirm current pricing and availability at time of call, as material costs and crew schedules shift seasonally.
United Home Services fills a practical gap for Baltimore homeowners facing aging insulation or energy losses in attics without major structural complications. Its transparent pricing and same-crew accountability make it a reliable entry point for a common upgrade.
