Intro: Longevity isn’t promised — it’s proven
A Solidor door isn’t just designed to look good on day one.
It’s engineered to perform year after year, through changing seasons, constant use, and real British weather.
The Solidor guarantee exists because longevity is built into every part of the door — from its solid timber core to its UV-stable finish and high-grade hardware.
At Timber Composite Doors, we’ve been supporting Solidor customers since 2008, giving us unmatched insight into how these doors perform over decades, not months.
This guide explains exactly what the Solidor guarantee covers, why claims are so rare, and how professional aftercare protects long-term reliability.
1. The Backbone of the Guarantee: Quality that doesn’t fail
Every Solidor is backed by a full 10-year manufacturer’s warranty, but the real confidence comes from the stats behind it:
| Component | Coverage | Expected Lifespan |
|---|---|---|
| Door Slab (Timber Core) | 10 years | 20–25 years |
| Colour Finish | 10 years (UV-stable) | 20+ years |
| Frame & Cassettes | 10 years | 20 years |
| Hardware (Hinges, Handles, Locks) | 5–10 years | 15–20 years |
That coverage isn’t window dressing — it’s a direct reflection of how long Solidor products actually perform in the real world.
And because we’ve installed over 100,000 of them, we know this guarantee holds up.
2. The Solidor Difference: Real warranty, not fine print
Let’s be blunt — not all warranties mean what they say.
Some brands bury exclusions in small print, leaving homeowners stranded between manufacturer and installer.
Solidor and Timber Composite Doors don’t work that way.
When you buy through us:
- You register directly with the manufacturer for product warranty.
- We handle all installation and workmanship cover.
- You get a single point of contact — us — for everything.
No blame game. No passing the buck.
If there’s an issue, we fix it. Period.
3. The Timber Core Advantage: Built to outlast the paper it’s written on
The most reassuring part of Solidor’s guarantee isn’t the coverage — it’s how rarely it’s needed.
That’s thanks to the engineered timber core, which provides unbeatable structural stability.
In 17 years of fitting, our warranty data shows:
- <1% of Solidor doors required any form of warranty claim.
- 98% of claims were minor hardware or cosmetic issues.
- 0% failures of the core or structure itself.
That’s unheard of in the door industry — and it’s why Solidor can afford to guarantee what others can’t.
4. What the Guarantee Covers
Here’s a breakdown of what Solidor’s warranty includes — and why it’s so comprehensive:
✅ Door Slab:
Guaranteed against warping, splitting, or structural failure for 10 years.
The solid timber core resists deformation even in extreme heat or cold.
✅ Surface Finish:
Colour and texture guaranteed for 10 years against fading, peeling, or cracking.
The thermo-plastic skin is UV-stable, weather-tested, and lead-free.
✅ Glazing:
Cassettes and units covered for seal failure or moisture ingress.
✅ Hardware:
Locks, hinges, handles, knockers, and letterplates covered against corrosion and malfunction (5–10 years depending on finish).
✅ Frame:
Fully covered against deformation, water ingress, or joint failure.
✅ Installation:
When fitted by Timber Composite Doors, you get an additional 10-year installation warranty, covering workmanship, alignment, and sealing.
5. What’s Not Covered — And Why
Transparency builds trust, so here’s what most warranties (including Solidor’s) exclude — and why it makes sense:
- Damage caused by improper installation (covered when we install).
- Physical damage or misuse (slamming, impact, etc.).
- Unauthorised modifications (aftermarket locks, cut-outs).
- Poor maintenance — especially ignored hinges or seals.
The good news? With a professional installation and two minutes of hinge care twice a year, you’ll never need to worry about exclusions.
6. How to Register Your Solidor Guarantee
Registering is simple — and we do it for you.
When your Solidor is installed by Timber Composite Doors:
- You receive a registration pack with your door’s serial number.
- We log it with Solidor directly (you get a confirmation email).
- You get immediate manufacturer coverage, plus our extended installation guarantee.
If you ever sell your home, the warranty can even be transferred to the new owner — another reason Solidors add resale value.
7. Our Aftercare Promise: Real people, real support
Our aftercare team is one of the few in the industry dedicated solely to post-install support.
They handle warranty queries, hinge adjustments, and even advice on cleaning and maintenance.
Our stats since 2008:
- Average response time: under 24 hours.
- 97% of minor issues resolved remotely.
- On-site repairs (if ever needed): completed within 7 days.
Because we’ve fitted more Solidors than anyone else, we don’t need to guess the fix — we already know it.
They didn’t just install the door and disappear. Two years later I called about a hinge, and it was sorted within 48 hours. You don’t get that kind of service anymore.

8. Extended Peace of Mind: The Timber Composite Doors Standard
We go further than Solidor’s baseline. Every full installation through us includes:
- Free post-installation quality check.
- Complimentary care guide.
- Priority access to our service and warranty teams.
We don’t just rely on the manufacturer — we add our own commitment.
That’s why homeowners keep choosing us even after 17 years.
When we say “fitted for life,” we mean it.
9. Why a Genuine Solidor Is the Safest Investment
The difference between a Solidor and an imitation often becomes clear years later — when something goes wrong and no one answers the phone.
When you buy from Timber Composite Doors, you’re covered from every angle:
- Manufacturer warranty
- Installer warranty
- Aftercare service
- Proven reliability
That’s why we remain the only Solidor supplier confident enough to say:
You’ll stop thinking about your door after we fit it — because it’ll just work.
