Absolute Building Solutions LLC, also known as ABS Roofing and Remodeling, provides residential roofing and home improvement services in Connecticut. Established in 2014, the company began with general home renovations and has since refocused its work on roofing, including roof replacement, repair, and storm damage restoration with insurance claim assistance. In addition to roofing, services include remodeling projects such as bathroom renovations, window and door installation, flooring, and lighting upgrades. The Hartford county based company serves all of the states communities as a locally owned and family-operated business.

"Please see attached image for details Brian and ABS bring top notch customer service, consultation and knowledge to roofing, building and remodeling. They are timely, communicative and ensure that we as homeowners know all angles of a job. Top level craftsmanship and attention to detail they provide an incredible end project. They replaced our roof which is a steep tricky roof and were able to get it done in one day. Where our first floor roof meets the siding we had some rot on some siding along the roof edge. Brian looked closer and said half the roofline needed to be cut out. Instead of just replacing the bad siding, Brian cut out a line across the entire edge so that it would look uniform. He fixed and replaced the flashing and covered it with plastic wood. He recommended this for aesthetics and to help prevent any further degradation. Adding an additional unforeseen cost, we feel that the cost was competitive and fair for the amount of time, material and attention to detail. "

Window Door Contractors questions, answered by experts

If you’re installing a pocket door into an existing door opening, the new space will need to be twice the width of the existing door, plus an inch. You'll need to double that number if you’re adding dual pocket doors.

Yes, solid-core doors can provide effective sound insulation for privacy-sensitive areas.

If a wooden door swells from temporary humidity or moisture, it should return to its original size as the environment dries out. However, if the door remains swollen due to prolonged exposure to moisture or water damage, it may not fully revert to its original shape and could require repairs or replacement. Using a dehumidifier and ensuring your doorway has good ventilation can help prevent and reduce swelling in wooden doors.

You might be able to turn a normal door into a fire-rated door, but you’re better off purchasing one that meets all NFPA 80 standards. If you want to DIY a normal door into a fire door, you’ll need a self-adhesive intumescent seal, metal hinges, fire-resistant glazing, and a self-closing device, but you’re always better off buying a certified fire door.

Most modern door knobs will all fit in standard, modern doors, so if you know your door was made in the last 50 years or so, you should be fine buying a standard replacement door knob. The only exception would be a thumb latch handleset for an exterior door, as this type of door knob may not fit your door without drilling a mounting hole for the bottom of the handle. Antique or custom doors might also have different sizes and knob mounting holes, so call in a professional if you don’t believe your door is a standard one.
