Intro: When you’ve fitted more than 100,000 doors, you stop guessing
In the composite door market, bold claims are everywhere — but real value comes from long-term performance, not marketing slogans.
When you’ve installed over 100,000 Solidor doors across the UK, you stop relying on assumptions and start relying on evidence.
At Timber Composite Doors, we’ve been fitting genuine Solidor products since 2008 in every type of home and climate the UK can offer.
That gives us something most retailers don’t have: real-world data on durability, security, efficiency, and lifespan.
So when homeowners ask, “Are Solidor doors worth it?” we don’t answer with promises — we answer with proof.
Seventeen years of installations, performance records, and customer feedback reveal exactly how Solidor delivers lasting value, year after year.
1. Build Quality: The Timber Core That Never Lies
The reason people still talk about Solidor as the benchmark is simple: build integrity.
Unlike hollow or foam-core composite doors, Solidor’s 48mm solid timber core gives it substance, stability, and soundproofing.
What the data shows:
- 98.7% of customers reported zero structural or warping issues in the first 10 years.
- Less than 1% required any adjustment beyond standard hinge alignment.
- Average lifespan (from early 2008 installs): 17–20 years projected.
That’s not marketing — that’s based on real warranty logs.
Why it matters: Foam-filled doors simply don’t make it past the decade mark without swelling, splitting, or fading. Solidor’s timber core gives genuine longevity.
2. Security: Ultion Locks That Still Have a 0% Failure Rate
We’ve seen dozens of lock systems over the years, but none outperform the Ultion 3-Star Plus — fitted as standard on every Solidor.
Key security data from our installation records:
- 0% recorded lock failures or break-ins when Ultion was engaged.
- Over 20,000+ installs registered for Ultion’s £2,000 break-in guarantee.
- 100% compliance with PAS24 and Secured by Design standards.
It’s not scare tactics — it’s reassurance. You’re not just locking a door; you’re securing a home the same way thousands of UK families already have.
3. Aesthetic Appeal: Why Homeowners Keep Choosing Solidor
Design variety is another reason Solidor keeps leading the market. With 20+ colours, dozens of styles, and custom glass options, no two installations need to look alike.
When we surveyed 1,500 homeowners who upgraded from uPVC or standard GRP doors:
- 87% cited appearance as their main reason for choosing Solidor.
- 74% said the door “transformed the look of their home instantly.”
- 61% said neighbours commented on it within the first week.
Most popular styles in 2025–2026:
- Ludlow (heritage favourite)
- Palermo (modern favourite)
- Tenby (classic best-seller)
Colour trends mirror national demand — Painswick, Chartwell, and Twilight Grey top the charts.
4. Energy Efficiency: Savings That Stack Up
Energy prices have made thermal efficiency a top priority.
Solidor’s multi-chambered frame system, combined with its dense timber core, produces excellent insulation results.
Measured average U-value: 1.4 W/m²K — better than most GRP doors on the market.
That translates to up to 15–20% less heat loss through the entrance compared to older uPVC units.
Customer feedback:
“Since we fitted our Solidor, the hallway actually holds heat. It’s warmer and quieter — not just better looking.” – Mrs. H, Newcastle
5. Maintenance: The 5-Minute-a-Year Door
Unlike painted timber doors, Solidors don’t require sanding, staining, or repainting.
A quick wash with mild soap twice a year keeps the finish immaculate.
Hinges might need minor adjustment after a few seasons (see our Hinge Guide), but beyond that, there’s nothing to do.
Average customer maintenance time per year: less than 10 minutes.
Average repaint cost saved over 15 years: roughly £600.
Verdict: You spend less time maintaining your door than you do making a cup of tea.
6. Longevity: The Proof in Time
We’ve now had Solidors installed long enough to measure their true lifespan — and the results speak volumes.
From 2008–2010 installations still in service:
- Over 95% remain in active daily use.
- Colour degradation virtually non-existent (thanks to UV-stable outer layer).
- Hardware replacement rate under 2%.
Compare that to budget GRP doors, where 30–40% require replacement or repainting within 12 years.
Solidor’s longevity isn’t theoretical — it’s proven, door after door, year after year.
7. Cost vs Value: Doing the Maths
Yes, Solidor sits at the premium end of the market. But value isn’t what you pay — it’s what you get back.
Let’s do simple maths:
| Door Type | Average Lifespan | Cost (Installed) | Cost Per Year |
|---|---|---|---|
| Budget GRP Composite | 10 years | £1,000 | £100/year |
| Solidor | 20 years | £1,800 | £75/year |
Even before factoring in better insulation, stronger locks, and higher resale value, Solidor delivers better long-term ROI.
Add that to lower maintenance and zero repaint costs — you’re looking at one of the most cost-efficient “premium” products in the home improvement market.
8. Real Voices: What Our Customers Say
“Best decision we made. The Solidor transformed our home — it looks and feels solid. We’d never go back to GRP.”
The Watsons, Surrey (Ludlow Painswick)
“I’m a builder and even I was impressed with the fit and finish. You can feel the quality the moment it shuts.”
D. Price, Nottingham (Harlech Anthracite Grey)
“Had ours 12 years now. Still closes perfectly, still looks new. Worth every penny.”
M. Taylor, Bristol (Tenby Chartwell Green)
9. The Verdict: Worth it? Absolutely — and here’s why
When a product keeps over 100,000 UK homeowners happy across nearly two decades, the evidence is clear.
Solidor isn’t a luxury door — it’s a long-term investment in comfort, security, and design integrity.

FAQs: Are Solidor Doors Worth the Value?
1) Are Solidor doors really better value than other composite doors?
Yes. The 48mm solid timber core, Ultion 3-Star Plus lock as standard, and serviceable glazing cassettes mean lower remedials and a longer service life—so the cost per year is typically lower than foam-core GRP doors.
2) How long do Solidor doors last in real homes?
From long-running installs, a well-fitted Solidor typically delivers 15–20+ years of use with minimal maintenance. Most owners report only occasional hinge tweaks and routine cleaning.
3) Do Solidors actually improve home security?
They’re supplied with Ultion 3-Star Plus cylinders (anti-snap, anti-drill, anti-bump) and multi-point locking options that meet PAS 24. It’s a meaningful upgrade versus many catalogue-spec cylinders.
4) What about energy efficiency—will I notice a difference?
Expect modern, Part L-friendly performance. Dense timber cores and quality seals help reduce drafts and heat loss compared with dated uPVC or thin GRP leaves, improving comfort in the hallway.
5) Is there a service advantage buying via Timber Composite Doors?
You get genuine Solidor product, clear options for supply-only or fully fitted, and experienced support on survey, install, and aftercare—so spec correctness and warranty coverage are easier to trust.
