Where cheap genuinely goes wrong
Some corners cut to hit a low price show up within a couple of years, not at the point of sale, which is exactly why they're worth understanding before you buy rather than after.
- Thin, low chamber count profiles that flex and lose insulation value
- No steel reinforcement in larger sashes, leading to sag over time
- Cheap hardware, handles and hinges that wear or seize early
- Silicone smeared around a gap instead of proper making good
- No certificate at all, leaving no paper trail for Building Regs
- A company that disappears and reappears under a new name (a 'phoenix' company) once guarantee claims start
Why these cuts are hard to spot at quote stage
A thin profile still looks like a normal white window in a photo, and a company with no fitting team of its own can still turn up with a van on the day. The tell is usually in the paperwork, not the showroom, which is why the quote checklist and certification matter more than the glossy leaflet handed over on the doorstep.
What affordable done properly actually looks like
There's a genuine way to keep prices low that has nothing to do with cutting the product. Low overheads, no showroom to maintain, no commission driven salespeople adding margin to close a sale, and a company that employs its own fitting team rather than paying multiple layers of subcontractor all take real cost out of the price without touching the spec.
| Where the saving comes from | Effect on the product |
|---|---|
| No showroom overhead | None, price only |
| No commission salespeople | None, price only |
| Own employed fitting team | Usually better accountability, not worse |
| Thinner profile / no reinforcement | Directly weakens the product |
| No certificate issued | Leaves you unprotected, not the product itself, but a real risk |
How this shows up at CW Doors
We're based from modest premises rather than a showroom, don't run a commission sales team, and use our own fitting team with over 40 years of hands on experience between us rather than subcontracting out. That's where our lower prices come from, and it's a different thing entirely to a thinner profile or a missing certificate.

Ask us directly what's in the spec, we'd rather you check than assume.
Questions worth asking before you judge a price
Ask what profile and chamber count is used, whether reinforcement is included in larger sashes, what the making good involves beyond sealant, and whether you'll receive a certificate. The answers tell you far more than the price alone, and a company confident in its spec will usually be happy to go through them.
A rough way to sanity check any quote
If a price sits well below everything else you've been quoted for what looks like the same product, ask specifically why. Sometimes the honest answer is simply lower overheads, in which case there's nothing to worry about. Other times the answer, once you dig, turns out to be a thinner spec or missing paperwork, and that's the point at which cheap stops being a bargain and starts being a risk.
It also helps to think a few years ahead rather than just at the moment of fitting. A window with a thin profile and no reinforcement might look identical to a properly specified one on day one, but the difference tends to show up as draughts, sagging sashes or stiff locks well before the guarantee period is up, by which point a phoenix company may no longer be around to help.
What this looks like for a landlord budgeting several units
A landlord replacing windows across a handful of rental properties has a different calculation to a homeowner doing one house once. The temptation to take the lowest of several quotes multiplied across several properties is understandable, but the same checks apply, and arguably matter more, since any weakness in the spec is then repeated across every unit rather than affecting a single home.
It's worth asking for the same chamber count, reinforcement and certification detail on a multi property job as you would on a single house, and keeping the paperwork for each address separately, since Building Regulations compliance and any future sale will be checked property by property, not as a job lot.
A simple test before you commit to any price
Whatever the quote, it's worth asking the installer to explain in their own words why their price is what it is. A company that can talk plainly about overheads, its fitting team and its spec without prompting is generally more reassuring than one that can only repeat the total figure. This costs nothing and takes a couple of minutes on the phone or at the survey.
