About our external mastic in Boughton Lees
Getting the depth right is half the job. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, leaving it bonded to two faces so it can move with the wall. Common call-outs are for movement joints with cracked, split or missing sealant and joints where the bead has come unstuck, on concrete & block, façade panels and render & cladding joints.
Around Boughton Lees, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Should I try it myself first?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

Boughton Lees buildings and the weather
Historic houses like Godinton House (about 3.4 miles south-west) are a reminder that the area around Boughton Lees 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.
Schools such as Towers School and Sixth Form Centre are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Homes close to Saint Christopher's Church include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant. Letting a property close to Wye station? Then split movement joints are easy to miss on a rental until damp shows inside.

Is Boughton Lees within the area you cover?

What does external mastic cost?
We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. You’ll get a clear quote before work begins.
When is the sealant fully cured?

For landlords and businesses
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
Keeping the joints in good condition
After the cure time, these simple habits help:
- Leave the joints unpainted unless we have said otherwise
- Wash walls gently around the sealant
- Keep movement joints as flexible joints, not mortar
- Get split or bare joints resealed while the damage is small
Do not paint over the new sealant unless we have said the product is paintable. Paint can crack on a flexible joint.
Small splits are the time to act. Then it’s a straightforward cut-out and reseal.
How it works
When we arrive, we look over the joints with you first, so you know exactly what we’re doing. We protect the surfaces around the joints before any work begins. Most jobs take a few hours for a handful of joints, longer for a whole elevation. In a small place like Boughton Lees, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we look over the joints with you, agree which to renew and talk through access.
- We cut out the failed sealant and rake out any dirt or growth.
- Both sides are cleaned back to sound material and primed if needed.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Before we arrive
- Let us know if you’ve seen damp or leaks
- For business premises, tell us about site rules or sign-in
- Keep pets and children clear of the area while we work

How the job changes by surface
Render joints
Render has movement joints and stop beads that need sealing. We reseal them with a flexible exterior sealant that suits the render colour.
Brickwork movement joints
People sometimes point up a brick movement joint by mistake. If that is happened, we rake it out and reseal it properly.
Why act early in Boughton Lees
Resealing a run of joints in one go is generally better than patching one at a time. Joints of the same age tend to fail together. In a small place like Boughton Lees, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you’re unsure, call 0345 464 0079 or send us an email and we will give you an honest view and a quote.
