Helping You To Maintain Your Products

Danetre Glass realise that full replacement is not always required when your products are not working effectively and will always advise clients on the best option for their requirements. Often, repair and maintenance work will extend the life of your existing double-glazed windows, doors or conservatories and their components, which is why we will sometimes suggest repairs rather than replacements. We offer a full repair service for windows and doors, with the added bonus of no call out charge and a completely free, no-obligation estimate for any work needed.

There’s no need to spend a fortune replacing defective windows and doors when our extensive repairs services cover various problems. Let our technicians come and assess any damage, and advise you on the best course of action.

Our Repair & Maintenance Services

Danetre Glass repair window handles and hinges, letterboxes, conservatories and leaking doors. We also specialise in the replacement of misted and broken double glazed units, lock changes and upgrades, anti-snap door barrel fitting and cat flap installation. Please take a look at our repair’s services below for more detail.

Replacement Of Glass Units

When your double-glazing unit becomes misty, this usually means that the seal has become defective and has allowed moisture to enter between the panels, causing condensation. While your initial reaction may be to completely replace the window, this is not always necessary. Danetre Glass can simply replace the glass panels, keeping the costs as minimal as possible. Whether the double glazing has cracked, smashed or broken, we are able to replace glass in windows and doors, completely eradicating any damage and condensation mist. After conducting a full assessment of your current product size, frames and material, we will be able to draw up a custom replacement service to provide you with a brand-new glass unit. As specialists in double glazing replacement, we guarantee to offer the most affordable service in the area while providing a reliable and efficient service. This service is suitable for:

  • Condensation on glass
  • Broken/cracked glass
  • Upgrade to double glazing
  • Single glazing replacement
  • Available for toughened
  • Available for fire-rated glass

Secure Door Repairs

Your doors are subject to harsh weather conditions, which can cause the features on your door to wear over time. Rather than having them completely replaced if you notice any damage, Danetre Glass can efficiently fix the problem, providing you with a cost-effective alternative to a full door replacement. As experts in door installation, Danetre Glass are able to quickly carry out any repairs and maintenance needed on your existing doors. We are used to dealing with doors of varying materials, such as uPVC and aluminium, so you can have peace of mind knowing that our technicians will know exactly how to carry out any work needed and will do so to an extremely high standard. We carry out a range of door repairs, including:

  • Smashed glass panes
  • Broken letterboxes
  • Defective hinges or locks
  • Incorrect alignment
  • Conservatory door repair
  • Damaged cat flaps

Lock, Hinge & Handle Repair

We understand maintaining smaller components such as locks, hinges, and handles is not always a priority. For this reason, it is common that they become broken, stiff or faded over time. However, when this happens, it can cause major disruption to the safety of your home. Unlike other installers, we see replacing the entire door or window as a last resort, and instead, we will always repair or replace the faulty or damaged component where possible.


The importance of your safety cannot be understated, which is why we will always repair or replace your faulty locks.


If you have loose or damaged hinges, our expert team can easily resolve the issue at a time that works best for you.


We understand how inconvenient it can be to have stiff or broken handles, so we endeavour to fix them with high-quality alternatives.

Lock Replacement & Upgrades

Fully functioning door and window locks are essential to keep you and your property safe. If you have a faulty lock or need it replaced entirely, our expert team are here to help. In order to prevent burglars from gaining access to your property, it is important to take extra safety precautions, so if you do notice a fault, please contact our team as soon as possible. Our replacement locks are an excellent option if you have lost your house keys or the lock has rusted over time and no longer providing safety. We understand replacement locks are sometimes needed urgently, which is why we endeavour to install them as soon as possible. When in need of a replacement look, we offer a variety of products that will keep you safe and deter intruders from entering your home. For example, high visibility window locks are a very popular choice because if a burglar breaks the glass, they still cannot open the window.

What Our Previous Clients Say

"I just wanted to say that the customer service at Danetre Glass is 10/10. When I contacted them to replace my broken letterbox, they were friendly and extremely helpful. I thought I would have to buy a new one, but after just one day, the existing one was all fixed with no issues along the way. Fantastic."
