"Simply put, you will NOT find a better, more honest, more helpful, more easy-to-work-with, reasonably priced contractor than John Lee and his crew at J & K Home Improvement & Restoration! We had a "complicated" set of circumstances when our home was damaged by a storm, last winter. The insurance company sent out an estimator to assess the damage and, after the company recommended J & K Home Improvement & Restoration, I was introduced to John Lee. I eventually learned that John also does estimates for a variety of insurance companies (because his company is so well regarded), and he patiently listened as I described the nuances associated with our house. During our initial consultation, he was able to clearly describe all of the steps that would be necessary and answer all of our questions. Long story short, not only was John able to address EVERY single concern and request that we had regarding the eventual repairs to the house (including roof, siding, and a window upgrade that would have cost much more if we had done it at a later time), but he spent plenty of extra time making sure that everything we had talked about was addressed to our 100% satisfaction! He was also able to persuade the insurance company to cover more complete repairs than was originally specified by the first adjuster! In addition, when we had an electrical "hiccup" associated with all the pounding on the walls, John quickly sent an expert electrician to locate and correct the problem. He absolutely could have passed those charges on to us because the failure wasn't due to any mistake on the part of his crew but, instead, he picked up the unanticipated expense himself. It was truly a pleasure to work with John! He made a difficult situation as easy to manage as possible, and we would strongly recommend J & K Home Improvement & Restoration to anyone who wants to hire a quality contractor that stands behind their work and well-earned reputation!"

Windows questions, answered by experts

Bay windows are not easy to install because they are heavy and require specific tools and woodworking experience. You’ll also need to install a roof cab, flashing, and shingles. Ensuring the window is level and sealed can be tricky but it is important because it prevents air leakage and water from entering your home. Most often, an experienced window pro should install bay windows.

Generally speaking, you should clean your windows and any associated fixtures and treatments every six months. Otherwise, clean them as needed to keep everything running smoothly. If you live in a part of the country with especially hard water, you may have to clean them three or four times per year, and the same goes for areas where insects, pollen, dirt, and other debris can soil your windows and potentially cause issues with the moving parts.

Costs depend on window size, type, material, and labor. Custom shapes or sizes typically incur higher expenses; full installation includes removing old windows.

Yes, professional window cleaning is worth the investment. Regular deep cleanings help keep your windows looking new, extend their lifespan, and boost your home's curb appeal. By removing dirt, dust, and other debris, you can reduce the risk of damage and accelerated wear to window frames and components. It also improves your home’s energy efficiency by keeping insulation and weatherstripping in good working order, potentially lowering your energy bills. Furthermore, annual or bi-annual cleanings can help identify problems like leaks or cracks early, before they escalate into expensive water damage. You can often recuperate the cost of cleaning through energy savings and by avoiding premature window replacement.

Glass block windows offer several unique benefits over traditional windows, and they create a much more unique look. These specialty windows offer added privacy while allowing natural light into the space, which is why they’re a popular choice for bathroom features. They also provide increased security as glass blocks do not open unlike traditional windows. Plus, they provide increased energy efficiency, lowering energy costs and preventing drafts.
