A great service from start to finish, 4 windows and a tricky cat flap in the conservatory - everything went exactly as planned and Robert and the team were so friendly and helpful - always on time, tidied everything as they went along and made us feel very confident in the work they were doing.  Delighted with the end result and would recommend to everyone!

Ellis who fitted my door was so happy and cheerful and so professional. If I was thinking of new windows etc I wouldn't go anywhere else. Dont think they would be beaten on price or workmanship.

 Trustindex verifies that the original source of the review is Google. Caledonia Windows & Doors installed my new composite Irish Oak door. The door and frame were of high quality, the installers made sure it fit perfectly. Installers worked very hard to do an excellent job including putting sheets down and cleaning all areas as they worked. The plastering had a few chips and they organised the plasterers to come out and fix chips within a couple of hours. Very impressed with works and also the customer service team. I would highly recommend this company for installing new doors, as love my new door & the service I received. ⭐⭐⭐⭐⭐

 Trustindex verifies that the original source of the review is Google. I absolutely love my new front door from Caledonia Windows & Doors. I highly recommend this company; their staff truly are their main asset. The salesman Robert was excellent when he visited my home, taking the time to talk me through all of my options clearly.The fitter, Ellis, was also fantastic. He was polite, courteous, and friendly throughout the installation, cleaned up after himself perfectly, and was highly professional from start to finish. Both are a real credit to the team.

Benefits of UPVC Windows

Cost Effective
Compared to other materials such as aluminium or wood, UPVC windows will usually be the most cost-effective option. The price of your UPVC windows in Cumbernauld will depend on the features you chose but they are still likely to be cheaper than the alternatives.

Virtually No Maintenance
One of the major benefits of UPVC windows is that they require very little maintenance. Other materials such as wood need to be repainted and probably require remedial refilling and patching as they tend to flake and rot over time. This will not happen with UPVC windows from Caledonia. They will never rot, rust, flake or fade. To keep them looking as new they only require the occasional wipe with a damp cloth.

Weatherproof
Our superior UPVC windows can withstand all the unpredictable Scottish weather can throw at them. Unlike wood which can swell in damp weather, our UPVC windows are completely storm and weatherproof. The UPVC non-porous properties means that water and damp cannot enter your home through the window frames. Also, they are non-corrosive which means they cannot be eroded by bad weather.

Benefits of UPVC Windows



Thermal Efficiency

Up to 30% of the heat in your home escapes through windows. Your UPVC windows from Caledonia have a high energy efficiency rating which means your home stays warm. It also has the added benefit of reducing your energy bills. Double glazing work by having two panes of glass separated by a layer of argon gas in a sealed unit. Argon gas is a poor heat conductor so when combined with the dual panes of glass prevents heat from escaping. Opting for triple glazing adds another pane of glass and layer of argon gas which increases the thermal efficiency of your UPVC windows.



Noise Insulation

As our UPVC double glazed windows are extremely well insulated, they also act as a barrier to noise. This keeps the inside of your home shielded from outside noise creating a quiet and peaceful environment for your family.



Durable

UPVC stands for unplasticised polyvinyl chloride and is a form of plastic. It has been proven to offer exceptional durability due to being non-porous, which makes it the ideal material for windows.
