"Did great work replacing a storm door and an exterior door for us - they look and work great, he even came back out six months later to make adjustments at no cost when one of them shifted a little with the weather."

"Joseph Donabella was the handyman that came and fixed my front door. I have not been able to use my deadbolt for years. Joe took the door off and refit it properly so I can now use my deadbolt again. My door knob lock was also sticking. After he checked it he said I needed to replace the door knob due to its age and suggested I go to a hardware store so I can get the new knob and get it rekeyed to my current key. He was very pleasant and professional. I would work with him again."

"I appreciated the candor and honesty and assistance in selecting the best type of door for my install. I also appreciated the price that I was offered. I was surprised that it would take so long (12 weeks) which will put the job out until Fall. But I am happy with the company and look forward to my new secure and beautiful back door!"

"I want to thank Jacob Tryon for selling me my Provia windows and sliding glass door. I want to thank the crew that installed them: Lorenzo, Ernesto, Pablo, Jonathan and Edgar. The crew removed and replaced 9 windows and a sliding glass door in 1 day! I also want to thank the 2 gentlemen that came and replaced the stucco, painting and replacing of my bars on my home. All the way through the whole process I was pleased with the professionalism. Everyone answered all my questions along the way. My Provia windows have more features then I knew. I absolutly LOVE them! I would recommend Flawless Solutions to anyone. I have already talked to some of my neighbors that asked about my new windows and my family."

Customers say: Quick response

"Very competent, honest, and knowledgeable in all areas of construction and codes - predicted issues before they came up. Came well prepared. It cost me more than I had hoped because I had not realized the change in support structure required or the complexity of the existing structure. It was still considerably cheaper than other bids and his bid was very detailed. Very good work and exhibited great care in not damaging anything else. Best carpenter I have used in Colorado and probably the best I have talked to. I would use him for anything he thinks he could handle. I trust him and his work."

Doors FAQs, answered by experts

You should rekey your house every three years to minimize the chances of someone gaining access to your home. You can do it more than that, but it depends on the level of foot traffic and visitors you get. Businesses, for instance, routinely rekey their locks every six months to a year. If you experience a break-in or a house key has gone missing, rekey the locks immediately. The same goes if your lock becomes damaged.

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.

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.

It’s possible to install a door yourself if the wall opening already exists, but the work is rather complicated, and a professional installation is usually well worth the investment. For your door to work and close properly, you’ll need to shim and level the door frame in your wall perfectly, which can be difficult. Additionally, we recommend you always hire a professional door installer to place an exterior door, as mistakes during the installation process can lead to poor security for your home.

Yes, but adding a deadbolt to some door materials, like steel, may make installation a little bit trickier. For these materials, you will want to hire a locksmith to do the work for you, but be aware that they may charge an additional fee of $25 to $50 or more.
