Window & Door Sealing in Sioux Falls, SD
Caulk, weatherstripping, and insulation to seal out drafts and pests.
Overview
About our window & door sealing service
Drafty windows and doors are the easiest energy loss to fix in a Sioux Falls home — and one of the easiest places for water and pests to sneak in. Sioux Fox Construction & Home Services seals windows and doors across the Sioux Empire so your home is quieter, drier, and cheaper to heat. We inspect every window and door for failed caulk, gaps at the frame, missing or compressed weatherstripping, and signs of water staining. We re-caulk exterior seams with paintable exterior-grade sealant, replace weatherstripping with the right profile, foam-seal hidden gaps with low-expansion spray foam, and install or repair thresholds where air pours in
Pest entry points around utility penetrations and sill plates get sealed too. Most homes see a noticeable difference in comfort and utility bills after a single visit.

FAQ
Frequently asked questions
How long does sealing take for a typical home?
Most homes are done in a single 4-7 hour visit.
Will this fix old single-pane windows?
Sealing helps significantly, but won't make a single-pane as efficient as new double-pane glass.
Do you replace bad windows too?
We focus on sealing and repair. For full window replacement we coordinate with a specialist.
What caulk do you use?
Paintable polyurethane or 100% silicone exterior sealants — long-life, weather-rated.
Is this part of weatherization?
Yes — it's the first step. We can also recommend insulation upgrades if needed.
