What we build

Whole projects, not just the trades in the middle.

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.

EXT

Extensions

Single and two-storey, side returns and wrap-arounds. Foundations, structural steels, roofing and glazing all handled in house.

CNV

Loft & garage conversions

Turning the space you already own into a bedroom, office or annexe, including Building Regulations sign-off.

KIT

Kitchens

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.

RST

Refurbishment & restoration

Sussex houses that need bringing back. Brick and flint repair, lime work, structural repairs and sympathetic rebuilds.

NEW

New builds

Detached houses and garden buildings from foundations up, including sustainable build methods and off-grid heating.

GLZ

Windows & doors

Our own glazing division. Supplied and fitted without the showroom markup, guaranteed for ten years.

How we work

Five stages, and you always know which one you’re in.

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 →

  1. Survey

    We come out, measure up and talk honestly about what’s possible and what it’s likely to cost.

  2. Drawings

    An architect from our trusted list, matched to your project, plus structural drawings and the planning and Building Regs applications.

  3. Clear quote

    An itemised written price for the work we’ve seen and agreed with you. Any extras are priced and agreed before they go ahead.

  4. Build

    A start date, a programme, and a named contact. Sheeted floors, dust extraction, swept site every evening.

  5. Handover

    Certificates, guarantees and sign-off in one file. We come back if anything needs putting right.

Architects

Come to us first. We’ll put you in touch with the right architect.

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.

Matched to your project

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.

Designs we can build

Their drawings are detailed the way we build, so the quote is clearer, and there are fewer surprises once work starts.

One team, start to finish

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

Why Sindall

Four reasons people keep our number.

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

Nearly every trade on our own books

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

We leave it cleaner than we found it

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

Windows without the showroom markup

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

Twenty years, one family

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

Two hundred reviews, and one recurring theme.

Independently collected and verified by Checkatrade. We can’t edit them, and we wouldn’t want to.
