Window fitting, door installation and repairs
Tell us what needs changing. We can discuss the products, the fitting and the work around the opening before putting a quote together.
Window installation
Replacing one window or planning a larger job? Send photos of the existing frames and tell us which openings need attention.
Door fitting
Entrance doors, garden doors and internal glazing need different fitting details. Tell us the product and how you want to use the opening.
Repairs and glass replacement
Describe the fault before choosing a replacement. We can discuss whether glazing, hardware or alignment needs attention.
What will the finished edges look like?
People understandably spend time choosing the frame. The inside sill, outside seal and finish around the opening deserve attention too.
Show us the area around the existing frame when you request a quote. Tiles, plaster, render and old trims can affect how the replacement is fitted and finished.
We will discuss the installation and making-good responsibilities before the work is agreed. That gives you a clearer picture of what happens after the old frame comes out.

Window supply and fitQuestions from Hertford homeowners
Does the quote include making good?
Ask us to set out the agreed finishes and responsibilities. The work needed depends on the opening and the condition around the existing frame.
Can I request installation only in Hertford?
Yes, fitting-only can be discussed where customer-supplied products are suitable. Product specification, measurement responsibility and site condition must be confirmed.
What information helps with a glazing quote?
Provide the location, photographs, approximate dimensions, proposed product and whether the opening already exists.
Can a faulty window or door be repaired instead?
Sometimes. Failed sealed units, hardware and alignment can differ from a damaged or unsuitable frame; an assessment determines the practical route.
Will permission or certification be needed?
Full replacement windows and doors can be subject to Building Regulations, and listed buildings or conservation restrictions can add requirements. Check the specific property before work starts.
