Our Approach
At TNT Construction, our door replacement process is built around transparency, education, and expert craftsmanship. We help you choose the right styles, materials, and finishes to match your home—and we keep you informed every step of the way.
Free consultation & measurement — we measure the opening, evaluate the existing frame, check for rot or damage, assess insulation, and discuss door styles, security features, and energy rating (e.g. U-factor, R-value).
Custom door selection & design help — we help you choose materials, finishes (paint/stain), glass styles (tempered, Low-E, decorative), hardware options (locks, handles, smart features).
Pre-installation prep — removal of old door and frame if necessary, inspect and repair the rough opening, ensure proper flashing, insulation, threshold, and seal.
Professional installation — precise alignment, correct anchoring, weather-proof flashing, sealants, thresholds, and trim.
Finish & quality check — test door swing and locks, inspect weather seals, ensure proper operation, clean all surfaces, and walk through with you.
Warranty, maintenance & follow-up — explain warranties on hardware, door material, labor; maintenance tips; follow up for any adjustments or issues.
