Independent on-site inspection of defective or disputed windows and doors.
A site inspection allows DMR to examine, photograph and measure the installation in person, helping separate genuine defects from assumptions and identify where further investigation may be required.
Starting from £450 + VAT. Standard travel included.
What happens during an inspection
Visual examination
Inspection of accessible frames, sashes, doors, glazing, seals, hardware, junctions, finishes and making good.
Relevant measurements
Measurements are recorded where they help establish sizing, alignment, clearances, operation or another reported issue.
Photographic evidence
Relevant conditions are photographed so the findings can be understood and referred to after the visit.
Technical observations
The inspection distinguishes visible facts, likely causes, limitations and points requiring further investigation.
Before the visit
A focused inspection starts with a clear scope.
Before booking, DMR reviews the reported problems, number of products, location and available documents. This ensures the quotation reflects the likely time on site and identifies any access requirements.
- Make products accessibleClear furniture and personal items where reasonably possible.
- Keep documents availableHave the quotation, drawings and complaint correspondence ready if they are relevant.
- Explain recent changesTell DMR about repairs, adjustments, redecorations or previous investigations.
A standard inspection is visual and non-destructive unless a different scope is agreed in writing.
Concealed conditions cannot always be confirmed without opening up. Where further investigation is needed, the limitation and recommended next step will be recorded.
After the inspection
Choose the level of written output your case needs.
The inspection fee covers the agreed visit and standard travel. A formal technical report is a separate service unless it is included in a combined quotation. DMR confirms this clearly before instruction.
Next step
Request an inspection quotation.
Provide the postcode, number of windows or doors and a short description of the problem. DMR will confirm availability and the total fee before booking.
