Quotes for external mastic in Purleigh
The price is agreed before any work begins. It’s based on:
- Mould in or behind the old joints
- How many rooms, windows or areas are involved
- How much old sealant there is and how hard it is to remove
- The number and length of the joints
Leaving a failed joint usually makes the job bigger, not smaller. If you are unsure, ring 0345 464 0079 or send us an email for an honest opinion and a quote.

How we handle external mastic in Purleigh
A movement joint is only as good as its depth. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, so it bonds to the two sides only and can stretch. Typical jobs include hard, crazed mastic that has stopped moving and sealant that has lost its bond to the brick or render, on copings & trims, render & cladding joints and façade panels.
In a village or hamlet like Purleigh, older cottages and farm buildings often stand in the open, where walls and rooflines take the weather head on. Gutter joints and wall joints there need a sealant that can flex and stay put.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or drop us an email.

Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What happens on the day
Once we are on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take a few hours to a few days, depending on the length of joint and the access. In a small place like Purleigh, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, the joints are inspected and the access agreed.
- We cut out the old mastic and rake out anything in the joint.
- The faces are brushed clean and primed where the product requires it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
Preparing for the visit
- For business premises, tell us about site rules or sign-in
- Let us know if you’ve seen damp or leaks
- Let us know about parking restrictions

Your questions about external mastic in Purleigh
I let a flat near North Fambridge station. Can you help?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear price.
Will you come out to Purleigh?
Yes. Purleigh is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises. We can talk about working times when we quote.
How do I get a quote for external mastic in Purleigh?
It depends on the job, so we quote each one individually. To get one, phone 0345 464 0079 or drop us an email with a short description of the job.
Should I point up the gap in my brickwork?
No. Rigid materials can’t move with the wall and the joint fails. Where a joint has been mortared, it can often be raked out and sealed properly.
What do you put in the joint?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Can new sealant go over the old?
No, because it fails. The old sealant always comes out first.
When it is not the sealant
We’d rather tell you now than do work that will not last, so here’s what sealant can’t put right:
- Walls that need new movement joints cut into them
- Movement that’s more than a sealant joint can take
- Cracks in the bricks or render themselves, away from the joints
If you’re not sure, just call 0345 464 0079 or send us an email and we’ll give you a straight answer.

What we’re called out for in Purleigh
Joints sealed without backing rod, or far too deep, rarely last. Sealant bonded to three sides has nowhere to go and rips as the joint opens.
The problems people usually mention when they call include:
- Sealant that has lost its bond to the brick or render
- Plants rooting in failed movement joints
- Cracked joints where brick meets render or frames
- Hard, crazed mastic that has stopped moving
If you look after a building such as Purleigh Community Primary School, its movement joints, gutters and trims need looking after like any other building’s.

What else we do in Purleigh
Outside joints around Purleigh
Purleigh is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you live in an older home near Parish Church of All Saints, an extension built onto an older house moves differently, and the joint between them takes the strain. Rented homes near North Fambridge station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.

A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
Why act early in Purleigh
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 damage spreads beyond the joint. Where a wall is exposed, as many are in small places like Purleigh, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
