Professional uPVC Window Repairs and Double Glazing Repairs in Sheffield

Not only are windows the ideal way to get light into our homes and businesses, but they are also vital for making rooms feel more spacious. Without windows and natural lighting, we can feel confined to a small and unwelcoming space. When windows get damaged, you need an expert who can fix the problems caused by faulty locks, etc.

Common uPVC Window Problems

Over the years, we have seen just about every kind of problem you could realistically imagine with uPVC windows in Sheffield. Like any other part of your home, the cause of the problem(s) you have can vary greatly. The team of experts at Lock & Key Sheffield will find a way to fix the problem. With a detailed analysis of your property, we will find the cause of the issue and restore order, security, and a sense of protection. Typical problems include:

Common uPVC Window Issues

While the ideal choice for most homes in Sheffield, UPVC windows are not perfect. They can still have issues as time goes on, and the cause of these issues can be hard to pinpoint without the right level of experience. In our day-to-day operations, we see issues such as the following on a regular basis:

Faulty or stiff locks and handles

When the handles on your windows, or the locks, start to give you problems, you know you have an issue that needs immediate attention. If your handles or locks feel like they resist you or feel stiff, they at least need to be maintained and cleaned to restore typical operation. We will assess your windows for the issues with your handles/locks and fix them ASAP.

Broken or worn hinges

When hinges on your windows start to fail you, it is natural to worry about the situation. Failing hinges are a clear sign of problems with the window and can lead to stiffness and resistance every time you open/close your window. We can find the cause of your hinge headaches and resolve them quickly.

Misted or foggy double glazing

Over time, we have seen many windows become fogged up; this can make it hard to see out the window, and you might even feel a noticeable draft around the window. If the seals on your window are damaged and the double-glazing has weakened, we can repair this issue or replace the seal.

Window that don't close properly

When you go to close your uPVC windows in Sheffield over, do you find that they resist you or do not close over fully? That can be a serious issue. Not only does it limit efficiency for energy and draft exclusion, but it can invite criminals to try their luck as well!

We make sure that these problems are resolved; we find the cause of the issue, and we put in place a barrier to stop the causation from worsening. Then, we get to work on fixing the problem, whether it is down to misalignment, warping, or physical damage.

Our accredited experts review the window’s entire structure, from the frame that the window sits within to the hinges and the handles. Whatever the problem is, we will find a way to get it fixed and make sure your windows close without resistance.

Stuck or jammed windows

Windows that feel overly stiff whenever they are opened or closed are a cause for concern for sure. If you have this issue, ignoring the problem will only make it work. Let us know if your windows feel stiff, and we can quickly work out what the problem is.

Draughty windows

We rely on our windows to keep our homes nice and warm, right? We expect that our windows will limit drafts and make sure that our homes feel a little bit more comfortable overall. However, if our windows fail to provide draft exclusion, you can find your energy bills skyrocketing during the winter!

If you have that issue, we will make sure that a solution is put in place ASAP to fix the issue and get your windows closed as well as new. From physical damage and misalignment to changes in the weather, we find out what the issue is and correct it immediately.

Lost my front door key on hols so was dreading getting back and having to wait around for a locksmith. Called Lock and Key they were here within half an hour took less than that to open the door and replace the lock. Given plenty of spare keys the locksmith was efficient and friendly and didn't cost the earth. Highly recommended.

Came within an hour Sunday evening. Explained and showed me the damage that had caused the jam and broken key and gave me a fair quote for the repair. Replaced the lock and handle mechanism and thoroughly checked everything, even adjusted the door mountings as they were out. Brilliant job and smashing fella, wholeheartedly recommend.

Having found that the French doors would not lock on Sunday evening I phoned lock and key Barnsley. I gave a description of the problem and John gave me a quote for what he thought the problem would be but explained if it was something else he may have to adjust the quote. He said he could be with me in 30 minutes, it was actually more like 20 minutes. He checked the lock and confirmed it was the issue we had discussed. John completed the required work promptly and with minimum fuss. He left me with a receipt for the work, after demonstrating the new lock working. Very happy with this service and would recommend.
