"Used AJ Perri in past satisfactorily but now... Furnace checkup rattling sound, tech said was due to inducer fan motor needs replacing (ball bearings). Signed agreement for $2,300, they were going to order a replacement, paid $1,175 deposit. Cancelled work before the tech left as we were going to have it done later - also looked up the cost of said motor on the manufacturer web site only $209! Billing department unavailable to have the "pending" charge removed from checking acct. Found cancellation form in paperwork, only includes mailing address with a 3 day only grace period (?). Unable to fax form as a fax # (on a different form only) just rings & rings. Had to scan and email form to general "info" address. Unable to get through to billing dept, never available. Given direct phone # for said dept which gives a recording "voice mailbox not set up" then disconnects. Homeowner fixed all rattling noises for $0 - was only loose screw inside fan motor mounting bracket. Not refunded yet."

Double D Construction has been serving Central New Jersey since 1995. We do complete residential and commercial construction, following up with you after the job is complete to make sure everything is done to your satisfaction. Our staff takes pride in the quality of our workmanship and provides custom designed service to meet your every need. Award winning.

"Just a few years ago, we hired Double D to remove all of the old bright yellow siding (40 years old) and remove both layers of old roofing. The goal was to replace the roof and figure out the best options for us regarding the siding. The owner came out, met with us, presented options and associated costs quite clearly. Ultimately, we choose a lovely shade of sage green siding and a gray roof. We could not be happier. The employees were polite and efficient. The work was done in a timely manner (less than two weeks) and still looks great. We had zero problems with Double D. I plan on using them again to update a section of the siding that had previously been covered by a back deck. IMPORTANT NOTE: My neighbors replaced their siding with another company even though we advised them that Double D’s pricing was spot on and extremely professional, with attention to detail. Five months after their siding was installed, huge swaths of siding fell off! And their contractor was no where to be found. That’s when they asked for Double D! You will not regret utilizing Double D and will appreciate the variety of services available."

FAQs for second story addition building service projects in Florham Park, NJ

For many homeowners, building up is worth the expense because it provides the extra bedrooms or living areas that can’t be accommodated within the existing footprint. A larger, updated home often commands a higher resale price, recouping a sizable share of the project cost while allowing you to stay in the neighborhood you love. Run the numbers with a real estate agent and contractor to ensure the expected return and day-to-day benefits align with your goals.

Whether it makes more sense to build up or out depends on your lot, budget, and local code. Building up preserves yard space and involves less foundation work, but you may need to vacate the home during construction. Building out avoids staircases and can proceed while you stay put; however, it encroaches on the yard and may face setback limits. Compare both options with your contractor before making a decision.

A structural engineer will first inspect the existing foundation for cracks, footings, and load capacity. Depending on the findings, the crew may pour new concrete footings, install steel or concrete piers, add reinforced beams, or tie additional rebar into the slab. These upgrades redistribute the weight of the new floor and bring the structure up to code. Your contractor will outline the specific reinforcement plan and timeline once the engineering report is complete.
