Hiring a builder for your Bognor Regis home should be exciting. Whether you're dreaming of a stunning house extension overlooking the seafront, a practical loft conversion to finally give the kids their own space, or a complete kitchen overhaul, choosing the right builder makes all the difference between a project you'll love and one you'll regret.
But here's the thing: we've seen it happen time and time again. Homeowners across West Sussex make the same avoidable mistakes when hiring a builder, and it costs them money, time, and a whole lot of stress.
The good news? You don't have to be one of them.
Let's walk through the seven most common mistakes Bognor Regis homeowners make when hiring a builder: and, more importantly, how to sidestep every single one.
Mistake #1: Skipping the Research Phase
We get it. You're eager to crack on with your project. Maybe you've found a builder through a quick Google search or a mate's recommendation, and you're ready to sign on the dotted line.
But rushing this stage is where problems start.
Not all builders are created equal. Some specialise in new builds, others in renovations. Some have experience with period properties (and there are plenty of those along the Bognor Regis coastline), while others focus on modern extensions.
How to avoid it:
Take your time. Look at the builder's previous work: do they have a track record with projects similar to yours? At Swanbourne Construction, we encourage potential clients to browse our previous projects before we even have a conversation. It gives you a real sense of what we do and how we do it.
Ask questions. Read reviews. And don't be afraid to request references from past clients in the local area.

Mistake #2: Ignoring Builder Reviews and Testimonials
Speaking of reviews: this one's a biggie.
It's tempting to take a builder at their word when they tell you they're brilliant. But would you book a holiday without checking TripAdvisor first? Probably not.
Online reviews, testimonials, and word-of-mouth recommendations give you an unfiltered look at what it's actually like to work with a builder. Are they reliable? Do they communicate well? Did they finish on time and on budget?
How to avoid it:
Look for builders with consistent, positive feedback across multiple platforms: Google, Checkatrade, the Federation of Master Builders, and local Facebook groups are all worth checking. Pay attention to how builders respond to any negative feedback too. A professional, constructive response tells you a lot about how they handle problems.
We're proud of the reputation we've built across Bognor Regis and the wider West Sussex area. Honest feedback from real homeowners is how we've grown: and it's something we take seriously.
Mistake #3: Not Asking About Project Timelines
Here's a scenario we've heard too many times: a homeowner hires a builder, work begins, and then… nothing. Weeks go by. The builder's juggling multiple jobs, and your project keeps getting bumped down the list.
Unclear timelines lead to frustration, delays, and unexpected costs.
How to avoid it:
Before you commit, ask direct questions. When can they start? How long will the project realistically take? What could cause delays, and how will they handle them?
A good builder will give you a clear, honest timeline: and stick to it. At Swanbourne Construction, we provide detailed project schedules upfront and keep you informed every step of the way. No guessing games, no radio silence.
Mistake #4: Not Requesting a Full, Itemised Quote
You'd be surprised how many homeowners accept a vague quote that simply says "kitchen renovation: £15,000" without breaking down the costs.
Then, halfway through the project, the extras start rolling in. Electrical work? That's extra. Plumbing? Extra. Disposal of old materials? You guessed it: extra.
A vague quote is a red flag.
How to avoid it:
Always request a fully itemised quote that breaks down labour, materials, and any additional costs. This protects you from nasty surprises and gives you a clear picture of where your money's going.
We believe in complete transparency. When you work with us on a loft conversion or full renovation, you'll receive a detailed quote that covers everything: no hidden fees, no awkward conversations later.

Mistake #5: Not Checking for Insurance and Accreditations
This might not be the most exciting topic, but trust us: it matters.
If a builder doesn't have adequate insurance and something goes wrong on your property, you could be left footing the bill. Damaged walls, injured workers, accidental flooding: without proper cover, you're exposed to serious financial risk.
How to avoid it:
Ask to see proof of public liability insurance and employer's liability insurance before any work begins. Check for relevant accreditations too: membership with bodies like the Federation of Master Builders shows a commitment to professional standards.
At Swanbourne Construction, we're fully insured and happy to provide documentation whenever you need it. It's just part of doing things properly.
Mistake #6: Signing an Unclear Contract (Or No Contract at All)
We've heard horror stories from Bognor Regis homeowners who started major building projects on nothing more than a handshake agreement.
Don't do it.
A proper contract protects both you and the builder. It sets out exactly what work will be done, when it will be completed, how much it will cost, and what happens if things change along the way.
How to avoid it:
Never start a project without a written contract. Make sure it includes:
- A detailed description of the work
- The total cost and payment schedule
- Start and completion dates
- Provisions for variations and additional work
- Warranty or guarantee information
If a builder is reluctant to put things in writing, walk away. At Swanbourne Construction, we use clear, straightforward contracts that leave nothing to interpretation. You'll know exactly what you're signing up for.

Mistake #7: Poor Communication From Day One
Ever tried to get hold of a tradesperson who just… doesn't reply? Emails go unanswered, calls go to voicemail, and you're left wondering what's happening with your own home.
Poor communication is one of the biggest complaints homeowners have about builders.
And honestly? It's completely avoidable.
How to avoid it:
Pay attention to how a builder communicates before you hire them. Are they responsive? Do they answer your questions clearly? Do they take the time to explain things without making you feel rushed?
If communication is patchy during the quoting stage, it's unlikely to improve once the project's underway.
We pride ourselves on keeping our clients in the loop at every stage. Whether you're planning a house extension in Chichester or a full renovation in Bognor Regis, you'll always know what's happening: and you'll always be able to reach us.
Choose Wisely, Build Confidently
Hiring a builder is a big decision. Your home is likely your most valuable asset, and the right builder will treat it with the respect and care it deserves.
By avoiding these seven common mistakes: doing your research, checking reviews, asking about timelines, getting a detailed quote, verifying insurance, signing a proper contract, and prioritising communication: you'll set yourself up for a smooth, stress-free project.
At Swanbourne Construction, we've built our reputation on doing things the right way. We're local, we're experienced, and we genuinely care about delivering results that make Bognor Regis homeowners proud of their homes.
