Using the wrong sealant is another common reason. A high-modulus or general-purpose sealant can be too rigid for a busy joint, and it tears off the sides.
People normally contact us after spotting something like this:
- Weeds or debris growing in open joints
- Brick movement joints where the sealant has split
- Water getting into walls through failed joints
- Leaking joints around cladding and façade panels
Managing a site like Hyde Heath Infant School? Then its movement joints, gutters and trims need looking after like any other building’s.

How we handle external mastic in Hyde End
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. We pick a colour that sits well with the wall so the line blends in. We work on concrete & block, copings & trims and brickwork movement joints, and people most often call us about sealant that has lost its bond to the brick or render and old sealant gone brittle and cracked.
External sealant needs dry, clean surfaces, so work around Hyde End is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.
A one-year guarantee comes with the work, just as it does everywhere we cover.

What external mastic looks like in Hyde End
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Cholesbury Manor House (about 3.7 miles north) are a reminder that the area around Hyde End has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.

What we do, step by step
A visit follows a simple pattern: we check the joints, protect the area around them, do the work and tidy away. Most jobs take a few hours to a few days, depending on the length of joint and the access. Somewhere as small as Hyde End, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by walking round the building and agreeing the joints and the access.
- We cut out the old mastic and rake out anything in the joint.
- Joint faces are cleaned back and primed if the sealant needs it.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
Preparing for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about any water getting in
- Keep pets and children clear of the area while we work

Questions from Hyde End
I let a flat near Great Missenden station. Can you help?
Yes, landlords and agents are among the people we work for. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we will give you a clear quote.
Do you cover Hyde End for external mastic?
Yes. Our work covers London and the South East, and Hyde End is part of that. Just ring 0345 464 0079 or drop us an email with a few details of the job.
Why do you put foam in the joint first?
Closed-cell backing rod sets the depth of the sealant and stops it sticking to the back of the joint. That way it bonds to the two sides only and can stretch.
How often do external joints need resealing?
There’s no fixed answer: sunny, exposed elevations and busy joints wear faster. Check them each year and reseal when they split or harden. Our work comes with a one-year guarantee.
Do you guarantee your work?
Yes. All our work carries a one-year guarantee.
Can you work on commercial sites?
Yes. Larger jobs can be planned room by room or area by area to suit the site.
Will it make a mess?
Tidy work is part of the job. We protect what’s around the joints, and the area is left clean when we finish.
Are you fully insured?
Yes, we’re fully insured.
Different surfaces, different methods
Joints between dissimilar materials
Each side of the joint may need its own preparation. Both surfaces are cleaned and primed as the product requires.
Concrete and blockwork
Concrete faces can be dusty and porous, so preparation is key. A primer goes on where the product requires one before sealing.
Leave it or put it right?
Pointing a movement joint with mortar might seem a neat fix, but it stops the joint moving. The movement then cracks the brickwork or render nearby. The correct repair is a flexible sealant with the right backing. In a small place like Hyde End, 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 generally makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, phone 0345 464 0079 or email us for an honest opinion and a quote.
