Questions we get a lot
Is the estimate really free?
Yes. We come out, look at the site, and give you a number. No charge and no obligation.
Which towns do you work in?
Boston, Dorchester, Malden, Cambridge, Everett and Revere. If you're close by, ask anyway.
Can I build an ADU on my lot?
It depends on your city and your lot. We check the zoning and the site with you before you spend money on drawings.
How long does a deck or addition take?
It depends on size, permits and weather. You'll get a timeline with your written estimate, not a guess on the phone.
