One of the common challenges we often get as a fitting team is in the case of replacing timber windows which have to be rebated behind the window boards and plaster boards.
Each replacement window project has it’s own unique challenges so we thought it would be good to show you the process we took on a specific project.
On this particular job, after liaison with the customers, it was decided that we had to finish the internals of the windows without the use of any trims.
Following our initial inspection of the window it was noted there was existing cracks between the plaster and the frame. This showed that there was movement between the window and the plaster boards and suggested that they were rebated windows, something exceptionally common with older windows (See Right).
Even though we could make a well educated guess of the construction of the existing frame, we still took great care by removing delicately cut sections so we could confirm our thoughts (See Left).
To minimise any damage we used a multi-tool between the frame and plaster to make sure there was no bond between the two and also on the window board so that we had a neat opening for the new window which would benefit the final finish on the inside (see Right).
On removal it was apparent that the window board had no actual support, due to the construction of the old rebated window (See Left). So, with the addition of packers and expanding foam, we made sure this issue was resolved so that there would be no movement in the future. (See Right)
The window was then fitted to our normal exacting standards and the inside was sealed using builders caulk, utilising masking tape to achieve a neat and uniform finish which was exceptionally pleasing to the eye. We also used the caulk on the reveals to rectify the already existing damage for that final ‘touch of finesse’ (See Left).
When we came to finishing the exterior of the windows, we had to work around the left over sealant from the original fixtures, which was very close to the corner of the brick. The bricks had a coarse grain structure which makes them prone to damage from impacts, so cleaning them free of the old sealant would risk causing visible damage to the outside of the property. Therefore we, after consultation with the customer, decided that trimming the window was the preferable option. We used 28mm trim and a silicone seal to hide the residual sealant and create a professional finish (See Right).
We believe it is important that you as a customer are fully informed of the challenges and recommended actions we are going to take on your property. Our fitting teams will advise you of any unforeseen challenges we come across and are more than happy to answer any questions you may have.
