Cape Cod Home Additions

A Cape Cod home addition
that looks like it was always there.

A wider kitchen, another bedroom, a suite for family. Built into the house you already own, matched to its roofline, its siding, and the way you live in it now.

The Standard

Why Cape Cod families add on with AJ.

AJ manages the addition from the town counter to the last coat of paint, with honest guidance at every step. Three things set the work apart.

  • 01Zoning and permits, carried for youWe check setbacks, lot coverage, and Title 5 septic capacity against your parcel before the drawings go far, because on the Cape a new bedroom is a septic question as much as a framing one. From the zoning filing through final inspection, the paperwork and the inspection schedule stay with us.
  • 02Structure resolved before anything opens upWe evaluate the existing headers, bearing walls, and footings first, so the new loads carry back to the ground the right way and the framing meets Cape Cod wind-zone standards. The new foundation goes to the same frost depth as the original, and the addition is framed into the existing roof rather than parked beside it.
  • 03A house you can still live inDust walls, sealed openings, and staged demolition keep the finished side of the home usable while the addition goes up. One manager runs the site, so at the start of each week you know who is working, what is happening, and what comes next.

New framing tied into an existing Cape Cod home, with the addition roofline matched to the original pitch
The Match

Measured off the house that is already there.

Siding exposure, window sightlines, trim profiles, and roof pitch are taken off the existing home and carried into the addition, so the new wing reads as part of the original. Where the old cedar has silvered, we plan for how the new shingles will weather in behind it.

The Tie-In

Weathertight before the old wall comes out.

The addition is framed, sheathed, and closed in before we open the existing wall, so the house stays dry and the finished rooms stay in use. New floors are set level to the original rather than close to it, and every valley and sidewall is flashed for wind-driven Cape rain.

The Long View

Square footage that earns its keep.

A first floor bedroom, an in-law suite with its own entry, a kitchen opened toward the water side of the house: additions like these change how the home lives day to day. Tight framing, full insulation, and coastal-rated windows keep the new rooms from costing more to heat than the ones they join.

By Record

Measured in additions you cannot pick out from the street.

Having new flooring installed at our Cape condo. Jean & AJ Home Builders were recommended and he was expedient in getting back to me. We are a very small project for them, but within 5 days he had the condo measured and a quote off to me. He was readily available to discuss the project and we are moving ahead with his company.

I cannot say enough positives about AJ Home Builders! They replaced a porch and installed 9 new windows. The work was impeccably done with an amazing attention to detail. The carpenters were thorough, tidy with warm quick smiles. We are so happy we found them and feel completely confident in recommending them!!!

Hired AJ Home Builders for work remodeling a bathroom and replacing windows. From the beginning, Jean and his team were committed to the customer and careful with the existing house (laying out barriers for controlling dust and dirt). Jean was easy to work with and his subs were very courteous.

I recommend strongly this finish carpentry and framing company. Anderson and Jean answered the phone when I called. That is a real plus. I had a rotten leaky skylight in my kitchen, so the work needed to be done quickly. The Team was at the house within 12 hours to survey the job and gave me a very reasonable estimate that night.

Jean and his team at AJ Home Builders did an excellent job refinishing our master bath. The workmanship was excellent and the estimate was spot on. The job was completed on time. He also coordinated the painting of the main interior living and dining rooms with cathedral ceilings. The painters were excellent, professional and courteous.

AJ Home Builders are by far the best in the business!!!! I recently had new siding, windows, and a large amount of renovations in my home (kitchen, bathroom, living and dining rooms) done. All of this work was by no means a small undertaking but AJ Home Builders gave me a first rate performance on all that was done.

Jean and his crew were very professional and did excellent work. He is very attentive doing exactly what I asked and has great patience for all the changes I made. I've had him for two projects (exterior house siding and recently building my mudroom and some interior work).
