Are your window frames and door frames in need of repair? Our years of experience qualifies us to deal with any window repair or door repair that is required. Window repairs are often as simple as cleaning of the mechanism and squaring things, the weatherstripping or hardware may also need to be replaced to restore them to their original efficiency. These services are all part of a quality window restoration.

Many homeowners now realize the benefits of pre-painted metal capping and wish to have this service performed in conjunction with their window repairs. We use pre-painted metal and we always use the highest quality caulking material to seal the exterior against moisture penetration. When comparing contractors be sure to ask if they are capable of properly assessing the window performance and make repairs as necessary. Many cladding contractors simply fasten metal to the exterior window frame without ever considering the condition of the window, many cladding contractors don't even bother to open your windows when they clad them, they just fasten pieces to the exterior. If they don't open and inspect the windows how can they determine the condition of the windows and what is required to restore them properly? Our customers want a complete solution to their window repairs and sometimes this includes the necessity to deal with the more challenging and difficult parts of a proper window restoration. Our combination of experience and high quality materials can eliminate the need to replace windows and door frames. Metal window cladding installed by an experienced and consciencious installer may be the only solution you require.

Are you comtemplating an upgrade of your windows to increase energy efficiency and comfort? We recommend that you first consider replacing only the glass in your present windows with energy efficient, modern, sealed units. This would allow you to keep your existing window frames while enjoying all of the benefits of reduced energy costs and a more comfortable home. This is a very attractive alternative to replacing your entire window and frame. Most windows are candidates for an upgrade of the glass to modern thermally-efficient sealed units. This combination of modern sealed-unit technology and quality pre-painted metal window cladding will meet your requirements when a thermal upgrade is necessary. Energy efficiency and low-maintenance are possible with your present window frames.

When you know that new windows are necessary let us provide a quote. Sometimes existing windows are not worth saving because they weren't very good to begin with or they've just suffered too much neglect. Many older windows were poorly designed and will never be very thermally efficient due to design flaws or poor materials used in production. We are very experienced with new window installations and materials. We have the knowledge and experience to provide you with a high quality installation and high quality finishing. Window installations require care and attention to detail to maximize the investment of time and money. Our decades of experience have taught us that good windows combined with experienced and conscientious installers will provide the value that you expect.

  • I recently used John's Window Capping to refinish all the windows in my 35 year old house and am pleased to recommend John highly and without reservation. The work was done with pride and care. They were extremely clean and very respectful of my home. My windows look new and modern and the outcome is wonderful. I highly recommend this company. CM Kidd
