Why it pays not to wait
Small problems around the home rarely fix themselves. Getting them looked at early usually means a simpler job.
Juggling trades
Coordinating several trades yourself adds stress and delay.
Poor finish
An extension that doesn't match the house looks out of place.
Overruns
Poorly managed builds overrun on time and budget.
Common mistake: forgetting services
Heating, plumbing and drainage need planning in from the start, not added as an afterthought.
Common mistake: vague plans
Starting without a clear scope leads to changes, delays and surprise costs.

Extensions in Egham and the surrounding area
Types of extension
Single-storey rear extensions, side extensions and wrap-arounds each suit different homes and plots. The right choice depends on your space, budget and how you want to use the room.
Common uses include kitchen-diners, open-plan living areas, extra bedrooms and additional bathrooms.
Blending in with your home
An extension should blend in with the existing property. Matching materials, rooflines and proportions makes the difference between an addition that looks right and one that looks tacked on.
Plumbing and heating built in
Because plumbing and heating are Bradley's trade, extending heating into the new space, moving pipework or adding a bathroom is planned in from the start.
That means the finished room is warm, and water and waste run properly without last-minute workarounds.
Managed from start to finish
We handle every stage of the build, so you have one point of contact. You'll get a clear quote before work starts.
Living through the build
Building an extension means some disruption, especially when the new space connects to the existing house. Planning when that happens helps keep your home usable for as long as possible.
We will talk you through which stages affect which parts of the house, so you can plan around the work rather than be surprised by it.
Why professional extensions matters
It's tempting to try a quick fix yourself or go with the cheapest option you can find. The trouble is that extensions work often happens behind walls, under floors and inside fittings, where mistakes stay hidden until they cause damage.
A qualified, insured engineer finds the actual cause, uses the right parts for your home and tests the work before leaving. That's what stops you paying twice for the same problem.
What to expect when you book
Call or WhatsApp Bradley on 07596 863549 and tell him what's going on. He'll ask a few questions, arrange a time and come and look at the job. Trade Square guarantees same-day service, and we're open 8:00am – 5:00pm.
When Bradley has seen the job, he explains what he's found and what your options are, then gives you a clear quote. Work only starts once you've agreed. When it's finished, everything is tested, your home is left tidy and Bradley checks you're happy.
Clear quotes and honest advice
Before any extensions work starts, you'll know what's being done, why it's needed and what it will cost. If there's more than one way to tackle the job, Bradley will explain the options side by side, including the simpler or cheaper route where it makes sense.
If something unexpected turns up once work is under way, such as hidden damage behind a wall or under a floor, we stop and talk to you before going any further. You stay in control of the job and the budget from start to finish.
Reliable // Local // Qualified isn't just a tagline. It's how every job is run: turn up when agreed, explain the work clearly, do it properly and leave the home tidy.
