Weatherstripping and Insulation Pricing for Handymen
Charge $25–$75 per door for weatherstripping replacement, $20–$50 per window, and $75–$150 for door sweep installation. Whole-house draft-proofing packages run $300–$600 for a typical 3-bedroom home. Attic hatch insulation costs $75–$150. Outlet and switch plate insulation runs $3–$5 per outlet. Set a minimum service charge of $150 for any energy efficiency visit.
Energy efficiency services are a growing handyman niche, especially as utility costs rise and homeowners look for affordable ways to reduce heating and cooling bills. Weatherstripping, draft-proofing, and minor insulation work require minimal investment in tools and materials but deliver measurable results that clients appreciate. This is also consultative work — you can inspect the home, identify air leaks, and propose a scope of work that positions you as a knowledgeable professional.
Door Weatherstripping Pricing
Door weatherstripping replacement is the most common energy efficiency job for handymen. Charge $25–$75 per door depending on the type of weatherstripping and door condition. Adhesive-backed foam tape is the simplest option ($3–$8 per roll from M-D Building Products or Frost King) but wears out in 1–2 years. V-strip (bronze or vinyl) is more durable and runs $5–$15 per door — it friction-fits into the door jamb groove and lasts 5–10 years. Compression weatherstripping with a metal flange and rubber or foam gasket ($8–$20 per door kit) provides the best seal and is nailed or screwed to the door stop. For exterior doors, also check the threshold condition — worn or damaged thresholds allow significant air infiltration. Threshold replacement costs $30–$60 for the part (M-D Building Products or Frost King adjustable thresholds) and $75–$150 for installation, which involves removing the old threshold, cutting the new one to fit, and shimming for a tight seal against the door sweep.
Door Sweep Installation
Door sweeps seal the gap between the bottom of the door and the threshold — one of the largest sources of air leakage in most homes. Charge $75–$150 per door for sweep installation, which includes selecting the correct type, trimming to fit, and adjusting for smooth operation. U-shaped door sweeps (like M-D Building Products or Frost King) slide onto the bottom of the door and are the easiest to install — $8–$15 for the sweep. Surface-mounted sweeps screw to the interior face of the door — $10–$20 each. Automatic door bottoms that retract when the door opens and drop when it closes are premium options ($30–$60 from brands like Pemko or National Guard) and work well on interior doors where a sweep would drag on carpet. For garage-to-house doors, install a heavy-duty sweep plus weatherstripping on all four sides — this door is a major energy and carbon monoxide infiltration point.
Window Draft-Proofing
Window weatherstripping replacement costs $20–$50 per window, with material costs of $3–$10 per window. For double-hung windows, replace the weatherstripping at the meeting rail (where upper and lower sashes meet) and in the channels where the sashes slide. V-strip weatherstripping works well for the channels, while adhesive-backed foam or rubber gaskets work for the meeting rail. Casement and awning windows use compression gaskets that press against the frame when the window is closed — these are typically manufacturer-specific, so identify the window brand before ordering. For clients who want maximum efficiency without full window replacement, interior window insulation film kits (3M Indoor Window Insulator Kit at $15–$25 for a 5-window pack) are an effective seasonal solution. Charge $15–$25 per window for film installation — the film shrinks tight with a hair dryer and creates a dead air space that reduces heat loss by 50–70%.
Outlet Insulation and Air Sealing
Electrical outlets and switch plates on exterior walls are surprisingly large sources of air leakage. Foam outlet gaskets ($5–$10 for a 24-pack from Frost King or M-D Building Products) install behind the cover plate in 30 seconds each. Charge $3–$5 per outlet for this service, or include it in a whole-house package. For larger penetrations — gaps around pipes, wires, and ducts that pass through exterior walls, floors, or ceilings — use expanding foam (Great Stuff Gaps & Cracks at $5–$8 per can) or fire-rated foam for penetrations near fireplaces and furnaces. Charge $10–$25 per penetration for sealing. Recessed light cans in insulated ceilings are another major leak point — install IC-rated airtight covers (Tenmat FF130E at $8–$12 each) over each can from the attic side. Charge $25–$40 per light for this service. A thorough air-sealing job on a typical home covers 20–40 outlets, 5–10 penetrations, and 4–8 recessed lights.
Attic Hatch and Crawlspace Insulation
Attic hatch insulation is a quick, high-impact job. Most attic access panels are uninsulated, creating a significant thermal bypass. Insulate the hatch by gluing rigid foam insulation (2-inch XPS foam board at $15–$25 per sheet) to the back of the panel and adding weatherstripping around the frame. Charge $75–$150 for this service — it takes 30–45 minutes and dramatically reduces heat loss. For pull-down attic stairs, an insulated attic stair cover (Battic Door at $40–$60 or a custom-built foam box) works well — charge $100–$200 installed. Crawlspace vent covers for winter sealing cost $15–$30 per vent for magnetic or foam covers — charge $25–$50 per vent installed. These are seasonal services — install in fall, remove in spring — creating a recurring revenue opportunity. Know your limits: full attic insulation blowing, spray foam, and vapor barrier installation are specialty contractor work.
Whole-House Draft-Proofing Packages
Package your energy efficiency services for maximum value and revenue. A "Basic Draft-Proofing Package" covers weatherstripping on all exterior doors (3–4 doors), door sweeps, and outlet insulation on exterior walls — price at $300–$450 for a typical home. A "Premium Energy Efficiency Package" adds window weatherstripping, attic hatch insulation, penetration sealing, and recessed light covers — price at $500–$800. Present these packages with estimated energy savings: the Department of Energy estimates that air sealing and weatherstripping can reduce heating and cooling costs by 10–20%, which translates to $100–$400 per year for most homeowners. This makes your service a clear ROI investment. Offer these packages in fall before heating season and in spring before cooling season for maximum client motivation.
Frequently Asked Questions
Charge $25–$75 per exterior door and $20–$50 per window for weatherstripping replacement. Whole-house packages covering all doors and windows run $300–$600 for a typical 3-bedroom home. Material costs are minimal ($3–$15 per door or window), so this is primarily a labor charge that reflects your expertise in selecting and installing the correct weatherstripping type.
