Extensions
Single and two-storey, side returns and wrap-arounds. Foundations, structural steels, roofing and glazing all handled in house.
Haywards Heath · Mid Sussex · Est. 2006
Extensions, conversions and new builds across Mid Sussex. A family firm with nearly every trade on our own books, so the job runs to one programme and one phone number.
What we build
From the first survey through to the last coat of paint. Groundworks, structure, first and second fix, glazing and finishes, run by the same team throughout.
Single and two-storey, side returns and wrap-arounds. Foundations, structural steels, roofing and glazing all handled in house.
Turning the space you already own into a bedroom, office or annexe, including Building Regulations sign-off.
High-end designer kitchens, designed with you, built and installed by our own team. The care of a boutique kitchen studio, with a building firm behind it.
Sussex houses that need bringing back. Brick and flint repair, lime work, structural repairs and sympathetic rebuilds.
Detached houses and garden buildings from foundations up, including sustainable build methods and off-grid heating.
Our own glazing division. Supplied and fitted without the showroom markup, guaranteed for ten years.
How we work
Most of what goes wrong on a building job goes wrong before anyone picks up a trowel. We get the detail right at the start, so you have a clear price from day one, and nothing is added without your say-so. Read the full process →
We come out, measure up and talk honestly about what’s possible and what it’s likely to cost.
An architect from our trusted list, matched to your project, plus structural drawings and the planning and Building Regs applications.
An itemised written price for the work we’ve seen and agreed with you. Any extras are priced and agreed before they go ahead.
A start date, a programme, and a named contact. Sheeted floors, dust extraction, swept site every evening.
Certificates, guarantees and sign-off in one file. We come back if anything needs putting right.
Architects
The right architect is key to a successful project. Over the years we’ve worked with a handful we trust, from the first sketch right through to completion. We know their work, they know how we build, and their designs are ones we can turn into reality.
A kitchen extension on a semi needs a different architect from a new house in the country. We know who is good at what, and we’ll suggest the one who fits.
Their drawings are detailed the way we build, so the quote is clearer, and there are fewer surprises once work starts.
The architect and the builder already know and trust each other, so nothing falls between the two of us.
Already have an architect? We’re just as happy to build from their drawings. Tell us about your project
Recent work
A 1930s semi opened up across the back to make one kitchen, dining and living space, with a new steel frame carrying the original rear wall.
Why Sindall
We’ve been building in Mid Sussex since 2006. Most of our work now comes from people who watched us do a neighbour’s house.
01 / In house
Groundworkers, bricklayers, carpenters, plasterers and glaziers who work for us, not for themselves. Fewer handovers, fewer gaps in the programme, and nobody to blame but us.
02 / On site
Dust extraction on every cut, floors sheeted, and the site swept at the end of each day. It’s the thing customers mention most often, and it’s deliberate.
03 / Glazing
No high street shop and no sales commission, so like-for-like double glazing costs less. And because builders fit it, we spot the lintel and cill problems a fitter would leave behind.
04 / Record
City & Guilds qualified, glazing guaranteed through the Glass & Glazing Federation, and more than 200 Checkatrade reviews rated almost entirely 10 out of 10.
What customers say
Independently collected and verified by Checkatrade. We can’t edit them, and we wouldn’t want to.
“No job is too big or too small. He is honest and hard working, his team are all excellent and friendly.”
“Anthony was totally focused on the build, always punctual polite and professional.”
“All work was neat and tidy and on time. Would have no hesitation using them again.”
Where we work
Based in Haywards Heath and working across Sussex. These are the towns and villages we’re in most often.
