"This company came to replace the glass in a double pane bay window because the gas seal round it leaked and was unable to see through it. The glass was replaced, paid $600 for the new glass. A month or so after the installation there was condensation build up inside the double glass. Callled the company, and was told they would correct the problem, if not able to they would refund our $600. Needless to say we had gotten every excuse and then weâ re told they donâ t remember doing a job at my home !! Never got a $$ back either.. But I would like to know if they were never hear at all, then why is there a picture of the front of my home on their website as soon as you download it, and the same picture on their photo gallery of work they have done?? I have filed with the Suffolk County Dept of Consumer Affairs !! FG Window Repair had and has avoided out calls to them !"

Window Door Contractors questions, answered by experts

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. 

Yes, door sills are necessary components for most doorways. They serve several crucial functions, including weatherproofing, structural support, and aesthetic enhancement. Without a door sill, you risk water infiltration, drafts, and potential damage to the door and surrounding structure. Therefore, while they may seem small and often overlooked, door sills play a significant role in maintaining the integrity and functionality of a building's entryways.

Most of the time, a squeaky door is the result of dry hinges, where metal parts rub together without enough lubrication. Dirt, dust, or rust can also build up inside the hinge and add to the friction. Loose screws or slight misalignment can shift things just enough to create that irritating squeaking noise. Worn-out hinges or swelling wood from humidity changes can also be part of the problem on older doors. A good cleaning and proper lubrication usually take care of it, but if the squeak sticks around, it’s worth checking for bigger issues with the hinges or alignment. 

Smart door locks are safe to use and are usually considered safer than traditional locks with keys. While all electronic devices can be hacked, that doesn’t happen nearly as frequently in real life as people may think. You can also invest in multiple locks of different types for enhanced security so you don’t rely solely on one smart lock.

A butterfly hinge—also known as a surface mount hinge or dovetail hinge—is exactly what it sounds like: a hinge that resembles a butterfly. This type of decorative hinge, which is mounted on the surface of a door or cabinet, consists of two panels. One panel is mounted on a stable surface like a door frame and the other is mounted on the surface you need to open. It hinges open and closed like the wings of a butterfly.
