"Had a technician come out to scope our drain line. He forgot the camera, so they had to return. The check was not cashed, so I feared this with all the fraud in the world this man had my check and could compromise the safety of it. Called 3X no return call Told me to call accounting and no one answered and the voicemail was not set up ??? Customer service is very, very bad. I would NEVER do business with them again!!!!"

FAQs for attic remodeling projects in Princeton, NJ

A loft conversion turns your unused attic or loft into a functional living space, like a bedroom or home office. Adding walls, ceilings, lighting, and even plumbing seamlessly integrates the new room with the rest of your home. It's a practical way to expand your living area and boost your property's value.

A loft is a finished and integrated living space created by converting an attic, while an attic is an isolated, unfinished area under the roof. The loft conversion process installs proper walls, ceilings, and utilities, transforming the space into a usable room that adds value to the home. In contrast, an attic remains largely unmodified and is typically reserved for storage.

Planning permission is required for a loft conversion because the project alters the structure and must meet strict building codes. A building permit, costing between $500 and $3,000, and mechanical permits, costing between $10 and $500 each, are mandatory. This regulatory process ensures safety, adherence to design standards, and the home's overall integrity during conversion.

A loft conversion takes several weeks because the project involves multiple phases, from design to finishing. The process requires careful planning, obtaining permits, executing structural changes, installing utilities, and completing final decorative work to ensure the converted area meets building codes and the homeowner’s requirements.

Choosing an alternative project instead of a loft conversion can be advantageous when a less complex project's return on investment is higher. Homeowners may opt for improvements like upgrading doors, windows, or adding a deck because these projects demand lower overall costs and fewer structural changes. Such alternatives can enhance home value and functionality with a more streamlined process.
