Ufton Green questions
Can you do external mastic in Ufton Green?
Yes, Ufton Green is within the area we cover. Our work covers London and the South East. Just call 0345 464 0079 or drop us an email with a few details of the job.
Do you work for landlords with property near Aldermaston station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can phone 0345 464 0079 or email us with the details for a clear quote.
How long does external mastic last?
It depends on the exposure, the movement and the product. Sealant is a maintenance item, so check the joints once a year and reseal when it splits.
What do you put in the joint?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Are you fully insured?
Yes. We’re fully insured, and we have been doing sealant work for more than 20 years.
Is it OK to seal over old sealant?
No, it won’t last. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.
Can you quote for more than one area?
Yes, and it often makes sense. Doing several areas at once is usually more efficient, so mention them when you ask for a quote.
Where are you based?
Our base is in Crawley, and we work across South East England, London and Scotland.
External mastic for homes and businesses in Ufton Green
A movement joint is only as good as its depth. 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. We work on render & cladding joints, copings & trims and brickwork movement joints, and people most often call us about damp patches traced to an open external joint and joints with sealant missing in places.
Older homes in small places like Ufton Green may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water normally gets in, and they need the right sealant at the right depth.
Big or small, you get the same 12-month guarantee in Ufton Green and across West Berkshire.

Leave it or put it right?
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That protects surfaces like brick, render and concrete. Too stiff a sealant can pull at the edges and break them. Around Ufton Green, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part.
Why choose Mr Mastic in Ufton Green
- Sanitary silicone with an anti-fungal additive in wet areas
- White, clear, grey or coloured to suit, where the product allows
- Full insurance on every job
- Every job guaranteed for a year

Keeping the joints in good condition
Looking after new joints is easy:
- Clear growth from the base of walls and joints
- Check the sealant is paintable before painting near it
- Keep high-pressure jets off the joints
- 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 and spoil the finish.
Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established.
What sealant work cannot fix
Before you book, it’s worth knowing the limits:
- Cracking across the wall rather than at a joint
- Structural movement, which needs a surveyor or engineer
- Rising or penetrating damp from elsewhere in the wall
If you are not sure, just phone 0345 464 0079 or drop us an email and we’ll give you a straight answer.

Landlords, agents and businesses in Ufton Green
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
When to call us in Ufton Green
Every building moves. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. The sealant in the movement joints takes that strain.
Common reasons people contact us include:
- Movement joints with cracked, split or missing sealant
- Leaking joints around cladding and façade panels
- Gaps where render, brick and frames meet
- Plants rooting in failed movement joints
Schools such as Sulhamstead and Ufton Nervet School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

- What the problem is, such as mould, gaps, leaks or cracking

How the visit works
Most of a good job is in the preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it usually takes a few hours to a few days, depending on the length of joint and the access. In a small place like Ufton Green, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- For indoor joints, keep the area dry beforehand if you can
- Tell us if parking is tricky

External mastic in Ufton Green: local notes
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For an older house near a landmark such as Church of St Peter, older walls, gutters and the joints where extensions meet them need a flexible sealant. Letting a property close to Aldermaston station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.
