Dan was extremely easy to work with. He made our families emergency renovation process simple and was always available for questions. His company did fantastic work in a timely manner and Everything fell within budget. I would definitely recommend Dan for all your home remodeling needs.

From the beginning of the porch being knocked down. To the rebuilding of my new enclosed porch. Dan and his workers were amazing people. Very professional and courteous people. Beautiful job from start to finish.

Dan and his team just added on a 12×12 composite deck to a existing deck at my home. It came out amazing and we are so happy with it. Dan and his team were excellent and will be using them in future projects, thank you Dan

Best construction company!!! Very responsible and professional. Always on time, always ready to answer all questions!!! Highly recommend to anyone looking either to build a house, to do extension, build a porch or something else. They do free estimates and do the job quickly.

Dan’s Construction just completed a Trex deck with two sets of stairs for me. I am thrilled with the outcome! Dan was pleasant and efficient in overseeing our deck project, his crew worked tirelessly to complete their work, despite bad weather and the issue of trash on my site…

I came across Dan’s Construction by accident while searching the internet and I’m glad I did. I read the reviews and checked out the company and contacted for an estimate. He was quick and professional and reached out enthusiastic to work…

Dan is super nice and easy to work with. His team worked all day to get our roof replaced which had damage down to the rafters. He is knowledgeable, fair and trustworthy. I highly recommend this company and will definitely hire them for future projects.

We called after seeing a recommendation on Facebook and we are very happy we did. We had them build a covered pergola off our back sliders, and since we live in a log home, we wanted rough hewn lumber. Not only did they order the perfect stuff…

Dan and his team completed a full replace of the deck, staircase and balcony at my home. From the beginning Dan was knowledgeable and responsive to my inquiry including being quick to respond to any changes to material or additional items…


Additions, garages and outbuildings
Granby's newer custom homes on wooded and hillside lots, and its antique colonials and farmhouses, make for two different kinds of addition. On the newer houses the structure is predictable; on the older ones, matching the original is most of the job. Space is the one thing Granby is not short of, which makes rear additions, wings, detached garages and outbuildings all straightforward here. The constraint moves to the site instead: access, drainage and what the septic can carry. We plan those first because they decide how much extra space is actually buildable.

Site work, foundation and drainage
On a Granby property the ground comes first. Access for concrete and lumber, where the water goes when the snow melts, and how far the addition sits from the well and the septic all decide the design. Foundations bear below the 42-inch frost line, and we grade so the water leaves the building rather than sitting against it. On a Granby hillside the foundation has to deal with the slope, and on a wooded lot access for concrete and lumber is worth checking before design starts.

A wing that suits the property
On a Granby property with room around it an addition can read as a wing rather than a bolt-on, which is usually the better result. We match roof pitch and materials with quality materials throughout, break the mass where it wants breaking, and place the glazing for what is actually outside the window.

Septic, wetlands and the building permit
On a Granby property that is not on town sewer, an addition that adds a bedroom is a septic capacity question for the local health department under the Connecticut Public Health Code before it is a building question at all. Work near wetlands brings in the inland wetlands commission. Both have their own timeline, so we settle them before design rather than after. The building permit is filed with the Granby Building Department.

Finishing it, plus remodeling and everything outside
A shell is the easy half. Whether the new living space works comes down to layout, daylight and mechanicals, so we plan those first, then handle bathroom remodeling inside the addition, updated finishes chosen to match the house, and insulation and windows for real energy efficiency. Most Granby additions turn into more than an addition, and that is usually the right call: our remodeling services cover roofing, siding, gutters, windows, doors, kitchens, bathrooms, decks and sunrooms, so the whole project runs on one schedule with one point of contact.

Common questions about home additions in Granby
Will adding a bedroom affect my septic?
If the property is not on town sewer, yes, and it is the first thing to settle. Under the Connecticut Public Health Code an added bedroom has to be reviewed against the septic system by the local health department before it is a building question at all, and the answer can change the design or the cost. A good share of Granby is not on sewer, so we check this before design work starts.
What does an addition cost in Granby?
On a Granby property the site work can be a real share of the cost: access, drainage, and whether the septic has to change to support the added bedroom. We price it after seeing the site, not over the phone, because access and ground conditions move the number. The estimate is free and itemized.
How long does the whole process take?
Septic and wetlands review, where they apply, run on their own timelines and can outlast the build. We start them first. The build itself is the predictable part; design and approvals are where the range comes from, which is why we start those first.

More about home additions in Granby
Site before structure on a Granby property
Granby sits at the top of the Farmington Valley below the Metacomet Ridge, with a lot of preserved open space. Housing runs to antique colonials and farmhouses alongside newer custom homes on wooded and hillside lots, and out here the site decides the project more than the house does.
Access for concrete and lumber, where the water runs when the snow goes, and how close the addition sits to the well and the septic all constrain the design. An addition that adds a bedroom can require septic capacity the existing system does not have, and that is worth knowing in week one rather than week six.
Granby has a lot of preserved open space, and many properties back onto woods or protected land. Where there are wetlands nearby, the inland wetlands commission has a say, and we check before the design is final.
Adding on in Granby, CT
Granby, Connecticut sits at the top of the Farmington Valley on the Massachusetts line, with Granby center at the crossing of Routes 10 and 20 and Salmon Brook running through.
With so much preserved open space, many Granby homes back onto woods or brooks, and work near wetlands can need inland wetlands review. We check that before the footprint is set.
On the hills toward the Metacomet Ridge, lots are steeper and driveways are longer. Getting concrete and lumber to the site is part of the plan, and a sloping lot can mean a taller foundation on one side.
How the season shapes the build
An addition in Granby has one deadline the calendar sets for us: get the shell closed in and weathertight before the cold. That makes the start date matter more than it does on most jobs, because a foundation poured in May and a foundation poured in September lead to very different winters.
Interior finish carries the cold months and is the right work for them. We would rather give you a date that holds than the earliest one we can say out loud.
Zoning and permits in Granby
Work in Granby is permitted by the Granby Building Department under the Connecticut State Building Code, and we file in our name so the code responsibility sits with us rather than with you. We are licensed in Connecticut as well as Massachusetts, and inspections are ours to schedule and meet.
An addition runs two approvals in parallel, and the zoning one is the slower half. Setbacks, lot coverage and height come from Granby's zoning code, and where the design cannot meet them the route is a hearing for a special permit or a variance. We establish which case you are in before design work starts, because it changes both the drawing and the timeline.
On a Granby property that is not on town sewer there is a third track: anything that adds a bedroom is a septic capacity question for the local health department under the Connecticut Public Health Code, and work near wetlands brings in the inland wetlands commission. Both are worth settling before design rather than after.
