The visit
Typical time on site: 4–6 hours
How you use the garage and how it connects to the house.
Polystyrene or polyurethane, with the R-value to match.
Door, springs sized for the extra weight, and new seals.
Balance and seals checked.
The details
Southern New Hampshire winters are hard on springs and seals, and we keep doors running from Nashua to the Lakes Region. With long, hard winters with heavy snow loads, springs that break in sub-zero mornings is one of the most common calls we get.
Across the Northeast and Ohio, an insulated door is one of the best upgrades for an attached garage. Polyurethane-insulated doors are the warmest and stiffest; polystyrene is a good mid-range choice.
Insulated doors are heavier, so the springs and sometimes the opener need to match.

Straight answers about repairs, new doors, pricing and scheduling.
For an attached, heated or lived-in garage, usually yes.
R-9 to R-12 is common; R-16 and up for heated garages in cold states.
Kits exist, but they add weight and need spring adjustment. A new insulated door works better.
