What changes on a Bath property

Most of what we do in Bath sits on Georgian limestone rather than the brick and pebbledash that dominates Bristol. That changes the specification before it changes the price: a solid lime-built wall needs a system that lets it breathe, and the wrong choice traps moisture in the masonry.

We survey every Bath property before quoting and tell you plainly whether external wall rendering is the right answer for your wall — including when it isn't.

Questions

Frequently Asked Questions

Everything you need to know about our external wall rendering service.

What's the difference between external wall rendering and house rendering?

They're the same thing — both terms refer to applying render to the outside walls of a property. "House rendering" is more commonly used for residential work; "external wall rendering" is the broader term that includes commercial and partial-elevation work.

Can you render over painted brickwork?

Yes, but the paint needs to be properly prepared first. We use a chemical paint remover or mechanical abrasion to key the surface, then apply a bonding primer before the base coat. If the paint is in poor condition or there are many layers, full removal may be necessary.

Do you render commercial properties?

Yes — we regularly render shop fronts, office buildings, pubs and industrial units across Bristol. Commercial work is typically quoted per elevation rather than per property, and we can work to your tenant's schedule including weekends.

How long does external wall rendering last?

A modern silicone or monocouche render system lasts 25-30 years on a Bristol property with proper maintenance. Acrylic systems last 15-20 years. Sand-and-cement and pebbledash systems (the ones we're typically replacing) last 10-20 years.

Can I render just one wall?

Yes — single-elevation rendering is one of our regular jobs. It's most commonly needed on north-facing walls that take the worst of the Bristol weather. Single-elevation work is proportionally more expensive per m² due to scaffold costs but is still very cost-effective compared with full re-render.

Is rendering messy?

There's some mess during the strip-off phase (chunks of old render falling) but we contain this with debris netting and tidy up at the end of each day. The application phase is very clean — render is mixed in a sealed tub and applied with trowel or spray.

Do you handle insurance work?

Yes — we work with most major insurers on storm damage, impact damage and escape-of-water claims. We can provide detailed quotes in the format insurers require and work with loss adjusters directly. £10m public liability insurance as standard.

What colours are available?

All major render systems offer 100+ standard colours covering BS 4800 and RAL ranges. Bespoke colour matching is available for a small premium. We bring physical colour charts to the site visit so you can see how different colours will look in your specific light conditions.

Do you render garages and outbuildings?

Yes — we regularly render detached garages, garden offices, summerhouses and outbuildings as standalone projects or as part of a full property render. Single-storey outbuildings can usually be rendered without scaffold, which keeps the cost down.

What warranty do you provide?

10-year manufacturer system warranty on all qualifying installations plus our own 10-year workmanship warranty. £10m public liability insurance. Free 12-month aftercare inspection on every job.
