    After a successful planning application. as our home is in a strict conservation area, the replacement windows designed and made by The Traditional Window & Conservatory Company are an exact copy of the originals in every detail Including the curved glazing, only now they have curved DOUBLE glazing! The old and the new are in perfect harmony. We are so pleased with the results in all respects that we have since had our front door replaced including all the original traditional decorative leads now encased in double glazing.

    I had delayed replacing the original windows to my Edwardian house as I feared losing the fine detail and elegance, but The Traditional Window & Conservatory Company were the answer!. They replicated the exact appearance of the original windows–but what an improvement to both the heatand sound insulation!!. I am delighted! The company employees and representative were also polite,helpful and efficient. Thank you.

    Before installation rooms and walkways are sheeted up andthe old windows are removed from site and disposed of. Our expert fitters will ensure the replacements are finished and trimmed off with internal stub sills, architrave and period trim to mirror the originals. The immediate walls surrounding the window are decorated where applicable to complete the finished look.

    Conservation Areas & Listed Buildings

    We are conversant with the requirements for planning and have undertaken many successful Planning applications and where required, successful appeals to The Planning Inspectorate.
