What’s included
This is the work itself, item by item. If your job does not need one of these, it is not on your estimate.
Three-season or four-season decision
We set out honestly what each one costs to build and to heat before you choose.
Zoning and permit review
Setbacks, lot coverage and permit requirements checked for the addition.
Foundation or deck structure
Piers, frost footings or a reinforced deck frame sized for the enclosure.
Framing and roof
Structure built and tied into the house, with the roof detailed so it does not leak at the join.
Glazing and doors
Windows, sliding or swing doors installed, flashed and sealed.
Insulation for year-round use
Walls, roof and floor insulated where the room is intended for winter use.
Heating and electrical
Power, lighting and a heat source installed by our trade partners.
Interior finishes
Ceiling, walls, trim and flooring suited to sun, temperature swing and condensation.
How it runs
Every job we take on follows the same sequence, from the first call to the walkthrough.

Where it goes, how big, and whether you want to use it in January.
We call you back
Within 24 hours, to talk through use, orientation and the existing structure.
