Case Study – Dormer Windows

Aluminium is an excellent solution for dormer windows.

The brief

The original part of the property already had two Dormer windows and our customer wanted to fit another two or three Dormer windows, replicating the existing style.

Our approach

We matched the old windows with new sub-frames for the new Dormer windows. The new sub-frames included the same level of detail on the frames. We also matched the details of the original windows exactly, so that the new matches the old throughout – even though the windows have been fitted at different times the result looks the same.

When the customer came into our showroom he showed us the plans of the extension he was going to build. We discussed materials and we completed a site visit of the property, so that we could check the age of the property and the existing windows. Initially, the customer had thought about replacing three or four Dormer windows. However, a decision was made to replace all of the existing windows with new sub-frames and new casements.

We worked with the local builder to ensure a superior finish to the project.

Product focus

We used products from the Alitherm Heritage range.

The result

The property now benefits from brand new Dormer windows, which work perfectly with the windows that were originally part of the property.


Our Google Reviews

  • A great experience with The Window Sanctuary. They supplied and installed some celestial windows and roof lights to a loft conversion that we carried out. It is a period property with original sash windows and it was important to us that the new windows were in keeping with the character of the original house. We are delighted with the finished product. The customer service was very good and they were amenable when our architect got carried away and the window sizes increased quite materially from the original quotation - thereby working hard to minimise the extra costs. The quotation process was quick and efficient. Their surveyor, Steve, was very professional and also had a strong technical knowledge to help advise us during the build stage. The installation team were very professional and worked extremely hard to get the windows fitted during poor weather. The lady on the front desk, Jeannette, was also very friendly/helpful despite my numerous calls to the office throughout the process. There were a few delays but this was the result of CoVid as opposed to anything in their control, and Simon worked hard to get the order pushed through the suppliers and installed promptly. I always like to support local businesses and this one did not disappoint. Will definitely use them again going forward for any further works. Thank you.

  • Fantastic service and quality products I had my front door replaced by The Window Sanctuary and I am delighted with the results. The fitters were punctual and polite. The process was so quick & easy and any queries I had were dealt with very efficiently. I have no hesitation in recommending this company and will definitely use them again in the future.

  • Really enjoyed dealing with the Window Sanctuary. The office team are very friendly and courteous and the installation team were good fun and very thorough. The finishing touches were beyond my expectations. We're delighted with our new windows and the enhanced view they provide.

  • From the start The Window Sanctuary were friendly and polite and a pleasure to deal with. They offered lots of advice, especially helpful as our installation was a little tricky. We also had lots of issues with our extension which caused delays our end, which The Window Sanctuary worked around, even though it meant the installation had to be carried out in two lots, when initially it was meant to happen in one go - they were very accommodating and patient, thank you! Would definitely recommend.

  • The Window Sanctuary replaced all my old Crittal Windows with slimline heritage aluminium windows to retain the period look of my grade 2 listed property and furthermore replaced the old rotten timber sash windows with new hardwood timber sash windows bringing the property back to life. The guys were hardworking very knowledgeable and very professional I wouldn’t hesitate to recommend this firm highly enough Warm regards Fraser Owen
