Garages & Additions

Guaranteed Builders & Developers, Inc. is a full-service garage builder located in Douglas, Massachusetts. 

Our model home and garage display -- located at 138 Main Street, Douglas -- is the largest in New England.  We are open Monday through Friday 10am to 6pm, Saturdays and Sundays 10am to 4pm. 

We have several models of stick-built garages to choose from.  Starting with the standard model, GBI can customize your structure to your exact needs and wants, including single and two-story options.  Garages can be built as a detached unit or attached to your home with or without a breezeway.  Garages are stick-built on-site with pre-engineered trusses on top with high quality materials throughout the building.  Matching the existing roof line and exterior of your home is possible.

For customized garage projects, we offer free in-home consultations.  We begin the garage design process with a quick call to discuss your preliminary ideas so our sales representatives can prepare options and ask the right questions.  We are always up-front with our prices, and start the design process by giving you a ballpark estimate. We always want our customers to be aware of the total cost as we customize each garage. Just because it’s your dream garage doesn’t mean it needs to have a sky-high price!

When our Construction Supervisors visit your home, they will measure the plot, discuss style and size of garage options optimal for your space, and supply siding and garage door samples.  A formal quote will be provided after the visit.

Give us a call at 508-476-1500 to schedule your free no-obligation site visit and quote.  For over fifty years, Guaranteed Builders & Devleopers has been building garages and additions throughout Massacusetts, Rhode Island and Connecticut.
