What the job involves on each surface
Concrete and blockwork
Concrete faces can be dusty and porous, so cleaning and priming matter. We prime where the sealant needs it before the bead.
Copings and trims
Joints in copings, parapets and trims are exposed to the worst of the weather. Each is resealed with a weatherproof, flexible sealant.
External mastic in Stanford in the Vale
We’re ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Some surfaces need a primer before sealing. Common call-outs are for sealant that has lost its bond to the brick or render and failed sealant between panels on a façade, across joints between brick and frames, brickwork movement joints and concrete & block.
Homes around Stanford in the Vale range from older cottages to newer houses, with walls and rooflines of every type. Older gutters and trims need their joints resealed; newer brick and render need their movement joints kept sound.
Big or small, you get the same 12-month guarantee.

What we do, step by step
All our tools and materials come with us in the van, so there’s nothing for you to buy. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours to a few days, depending on the length of joint and the access. For a job in Stanford in the Vale, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We start by walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- Let us know about earlier repairs to the joints

Advice
Landlord and commercial work in Stanford in the Vale

From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Why deal with it now?
Water gets in through a failed movement joint. Dealing with it early keeps the repair to the joint, rather than the wall around it. Homes in smaller places like Stanford in the Vale can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.

How to look after the new joints
To keep the joints looking good and working properly:
- Point out the joints to other trades
- Keep high-pressure jets off the joints
- Keep soil, plants and ivy away from the joints
- Have failed joints looked at early
Don’t let soil, plants or ivy build up against the new joints. Damp material against the sealant shortens its life.
Gaps, plants or missing sealant in a joint are worth getting looked at. Early work is quicker and leaves a better finish.
Walls and rooflines in Stanford in the Vale
Historic houses like Longworth House (about 4.7 miles north-east) are a reminder that the area around Stanford in the Vale has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For an older house near a landmark such as Church of St Denys, an extension built onto an older house moves differently, and the joint between them takes the strain. Managing a site like Stanford in the Vale Church of England Primary School? Then larger buildings have long runs of movement joint that eventually need resealing.

Why is there a gap in my brick wall?

Will there be a smell?
It depends on the product. Some products have a noticeable smell, others very little.
Can you seal joints between two different materials?
Yes. Materials like render, brick, metal and uPVC all move differently, so the joint between them must be flexible. We choose one that suits both surfaces.
