Checking Out Warranty Before Expiration
posted 13th July 2026
I was recently asked to visit a property in North London that had been built under an NHBC warranty. The client had experienced some issues with their roof, which they had dealt with themselves without involving the warranty provider. What concerned them more was the question of what else might be lurking that they hadn't noticed. Their warranty was entering its final six months.
Not All Cover Runs the Same Length
Most people assume their new-build warranty is a single ten-year guarantee, but it rarely works that way in practice. The structural element of the building, meaning the frame, foundations, and load-bearing walls, is typically what carries the full ten-year term. Other elements are covered for much shorter periods. Drainage, windows, and specialist items often fall away well before the structural cover expires, sometimes within the first two or three years.
This tiered structure catches a lot of homeowners out. They assume that because their warranty document says "10 years" on the cover, everything is protected for a decade. In reality, the elements most likely to develop hidden issues, such as drainage runs beneath the ground or specialist glazing systems, may already have fallen outside the cover long before the structural warranty period ends.
An Impressive Property, and a Timely Instruction
The property in question was a substantial one, arranged over four levels including a basement. My brief was straightforward: give the client an experienced structural surveyor's assessment of the building's condition while there was still time to make a claim, should anything come to light.
Having spent twenty years as an NHBC registered contractor before moving into surveying, I have a fairly clear picture of where problems tend to surface on this type of construction, and importantly, when. Certain defects announce themselves early. Others take years to become visible, often appearing just after the warranty has lapsed, which is precisely why a proactive inspection close to the expiry date is so valuable.
I was able to carry out a full inspection and turn the report around within a relatively short timeframe. I'm pleased to say that, from a structural point of view, the building was sound. No hidden issues, no cause for concern. The client was understandably relieved, and very pleased with the outcome.
The Pattern I See Too Often
Not every instruction ends this well, and that's really the point of writing this. I'm contacted regularly by homeowners who discover a significant issue only after their warranty has already expired. By that stage, the options for redress are far more limited, and the cost of putting things right falls squarely on them.
A structural problem that would have cost nothing to resolve under warranty can, once that cover has lapsed, become a five or six figure repair bill met entirely out of the homeowner's own pocket. The frustrating part is that many of these issues are detectable well in advance by someone who knows what to look for and where to look for it.
The Simple Takeaway
If your NHBC or other new-build warranty is approaching its expiry date, whether that's the ten-year structural cover or one of the shorter periods for drainage, windows, or specialist items, it's worth having an independent inspection carried out while you can still act on the findings. It's a modest cost against the potential exposure of finding a serious defect after the warranty has gone.
It's a simple piece of advice, but one that consistently proves its worth. Check it out before the cover runs out.
