Is it possible to install double glazing into my original sash windows:
It is possible to install double glazing into most original sash windows but each case is treated individually. Usually we install double glazing into your sash windows by renovating the original frame, tailor making new double glazed sashes to match original profiles and adding lead weights to balance the heavier window to give optimum ease of operation. Our draught proofing system also creates a seal around the sashes and frame, consequently eliminating noise and draughts. One of the many factors that people ask for double glazing in the first instance. For these reasons an individual survey is highly recommended where discussions can take place with regard to your needs and recommendations can be given for consideration.
Should I replace my existing timber windows with new timber windows:
Replacing your existing timber windows with new ones is not always necessary and this depends greatly on the condition of the timber. You will be amazed by the craftsmanship of our operatives and their skill at repairing rotten timber by either splicing in new timber or by the use of a two part epoxy resin wood repair system that restores areas where rotten timber has been removed back to its original strength. Replacement is only suggested in rare cases when it is considered the most effective solution.
Is there much disruption during installation:
The company wants to ensure the minimum disruption and inconvenience to our clients but inevitably there will be some disruption. An installation schedule is discussed with all our customers upon commencement to inform them of which windows will be renovated on which day. During the installation our operatives will contain themselves to one room at a time(where possible), dust sheets are placed around the surrounding areas and on completion of each window they will clean the immediate area and vacuum the carpets. All work is carried out internally and all we ask is that access is available to the window and that all valuables have been removed before we commence.
How long does it take to install:
Installation time depends on the size, location and condition of the window but generally speaking an operative will renovate and install our draught proofing system to one window per day.
Why shouldn’t I replace my windows with plastic ones:
Sash windows are our heritage and retaining them maintains the character of your property and the perception that replacing them with plastic means they will be maintenance free is untrue. Even in plastic windows there are frequent problems including the breakdown of the sealing gaskets, allowing water ingress and condensation between panes. Your original windowshave usually withstood centuries of wear and will continue to outlive modern substitutes as sash windows are made from seasoned timber by skilled craftsmen. With the ability to install draught proofing and even double glazing to your sash windows the need to replace them for plastic is reduced as newly renovated sash windows operate just as well.
