"I needed to have both my exterior doors replaced as I was losing heat around them last winter. I contacted Abraham and he came and took measurements and ordered the doors. He and his assistant installed the doors in 2 days working around my 5 labs. I'm a retired Army Engineer Major and have managed many construction projects. He did an excellent job. I would highly recommend him."

"He did a great job, very professional - put up curtain rod, wall remote holders and waterproof sealed around a counter top and back splash in my kitchen. He was very neat with the sealing work, so you can't see at all where it was applied. I will definitely hire again."

"

From sales to installation, the process was exceptionally smoothly and everything happened as was originally scheduled and promised. Communication was excellent, advice from the estimator was spot-on, the quality of the doors even better than what we expected and the installation was EXPERT. The doors look fabulous, work perfectly, and the installer did a much better job than what we could have done ourselves. We are so glad that we decided to outsource this service and we highly recommend this company.

"Excellent service having my garage ceiling drywalled. They arrived when they said they were going to and were super about cleaning up after the job. Every step was thoroughly explained, including why they chose the materials they did. They had 2 other businesses come in to handle a couple of things. They explained why they did that and still came in under the estimated cost for the job. I am very pleased and will definitely not hesitate to hire them in the future."

Doors questions, answered by experts

Yes, you need to install a sill for an exterior door. A sill offers structural support for the doorframe and creates a place to install the threshold, which is essential for keeping water from seeping underneath the door and into the home. Door sills are not necessary for interior doors.

Interior door thresholds are usually attached using finish nails, and some contractors will also use construction adhesive under the threshold to hold it in place. Exterior door thresholds are more commonly screwed to prevent them from pulling up when people step on the raised edge on the outside of the door. Exterior doors also include caulk sealant on the inside to prevent water and air from seeping through.

Start by checking the top or side edge of the door. Look for a certification label or metal tag stamped with details like the fire rating and information on the manufacturer. Even if it’s painted over, the tag should still be visible. Next, look along the edges for slim intumescent strips. They’re designed to swell up and seal gaps when exposed to heat. Finally, check if the door closes itself. Most fire doors have a self-closing mechanism, like an overhead closer or spring hinges. If none of these are obvious, contact a fire safety professional to help verify your door. 

Most modern, standard doors are 1 ⅜-inches thick, so you should aim for this thickness unless you're building a door to replace an antique door or fit into a non-standard wall opening. Thickness varies when installing a pocket door or sliding barn door, so a good rule of thumb is to measure your existing door, if possible. For standard doors, you can also measure from the inside of the door to the door stop to gauge the proper thickness.

New door knobs likely won’t have much of an effect on property value, but they can improve your home’s curb appeal and interior decor, which might lead some buyers to offer more for your home. However, in terms of personal value, adding new door knobs can be a game changer. New door knobs not only function better than older ones in most cases, but they make your home secure, and there’s a lot to be said about the peace of mind a new exterior door knob can provide.
