Searching "garden room builders near me" returns dozens of results. But how do you tell the difference between a quality company and one that'll leave you with problems? Here's our honest guide.
Red Flags to Watch For
Be cautious of companies that:
- Won't show you completed builds: If they can't take you to see a finished project, ask why
- Quote without a site visit: Every garden is different — a proper quote needs a proper survey
- Demand large upfront deposits: Industry standard is 10-20%, not 50%+
- Have no fixed business address: Check Companies House and verify they're a real, registered business
- Use stock photos: Their website should show their own work, not generic images
What Good Builders Have in Common
The best garden room companies will typically offer:
- A portfolio of real projects: With photos, locations, and ideally customer testimonials
- Fixed-price quotes: No surprises or hidden costs after you've committed
- Proper warranties: Structural warranty, plus guarantees on electrics and plumbing
- Building control sign-off: Where required, they handle the paperwork
- Clear timelines: A realistic build schedule with milestones
Questions to Ask Before You Commit
Put these to any builder you're considering:
- Can I visit a completed build?
- What insulation do you use and what U-value do your walls achieve?
- Is the electrical installation Part P certified?
- What happens if the build goes over schedule?
- Do you handle foundations and groundworks?
- What's your payment schedule?
Local vs National: Does It Matter?
There are advantages to choosing a local builder:
- Lower delivery and transport costs
- Easier to visit their previous work
- Better after-sales support
- Understanding of local planning requirements
- Accountability — they're part of your community
