"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."

FAQs for second story addition building service projects in New Castle, DE

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.
