External mastic for homes and businesses in Stanford Dingley
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant in a colour to suit. We work on brickwork movement joints, façade panels and render & cladding joints, and common reasons people get in touch are joints where the bead has come unstuck and movement joints with cracked, split or missing sealant.
In a village or hamlet like Stanford Dingley, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.
We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

Can I do it myself?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Questions from Stanford Dingley
Can you help a landlord with a rental near Aldermaston station?
Yes, we work for landlords and letting agents. Just call 0345 464 0079 or email us and tell us about the property, and we will give you a clear price.
Do you cover Stanford Dingley for external mastic?
Yes, Stanford Dingley is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or email us and let us know what needs doing, and we will give you a clear quote.
Is it OK to seal over old sealant?
No, because it fails. The old sealant always comes out first.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status and we are fully insured too.
Do you work for hotels and businesses?
Yes. We’ve worked for hotels, offices and other businesses and we’re fully insured.
Do you remove the old sealant?
Yes, every time. New sealant will not bond properly to old, so the joint is cleaned back first.
Should I point up the gap in my brickwork?
No. Mortar locks the joint solid, so the movement cracks the wall elsewhere. Use a flexible sealant with backing rod.
How do you reach high-level joints?
It depends on the building. We work on joints that can be reached safely. Tell us about the building and we will confirm what access is needed.
Honest limits
We’d rather tell you now than do work that won’t last, so here’s what sealant cannot put right:
- Movement that’s more than a sealant joint can take
- Cutting new joints into brickwork, which is building work rather than sealant work
- Cracked brickwork or render that needs a builder or plasterer
If in doubt, ring 0345 464 0079 or email us and we will say what we think before booking.
Surfaces we seal
- Render & cladding joints
- Copings & trims
- Concrete & block
- Brickwork movement joints

What else we do in Stanford Dingley
Why act early in Stanford Dingley
An open joint keeps letting water into the wall with every downpour. In cold weather, frost can damage wet brick and render near the open joint, so the problem grows beyond the joint itself. Older cottages and farmhouses around Stanford Dingley can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we will explain the quote if you ask.

Common problems we fix in Stanford Dingley
The wrong product in a moving joint is a classic cause. A stiff, general-purpose sealant cannot cope with a joint that moves a lot, so it pulls away from the edges.
The problems people generally mention when they call are:
- Joints pointed up with cement by mistake
- Cracked joints where brick meets render or frames
- Movement joints with cracked, split or missing sealant
- Damp patches traced to an open external joint
Rented homes near Aldermaston station change hands often, and split movement joints are easy to miss on a rental until damp shows inside.
Questions to ask before you book
- What insurance they hold
- Whether all the old sealant comes out first
- How long to leave it before use
- How hidden problems are handled
What happens on the day
You do not need to clear the whole room or building, only the area right around the joints. Everything nearby is protected, and the job takes a few hours to a few days, depending on the length of joint and the access for a typical job. In a small place like Stanford Dingley, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
- 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.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Getting ready for the visit
- Let us know about stairs, lifts or work at height
- Clear items away from the joints we’re working on
- Mention any leaks or damp you’ve noticed

Advice
Stanford Dingley buildings and the weather
Historic houses like Basildon Park (about 4.5 miles north-east) are a reminder that the area around Stanford Dingley 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. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
In the older streets around Church of St Denys, old and new materials meet at the roofline and walls, which is where sealant earns its keep.
