About our external mastic in Camberley
Short cuts in external joints show up within a season or two. Overfilled joints, missing backing rod and sealant laid over old sealant rarely last long. We strip the joint back and start again. We work on brickwork movement joints, joints between brick and frames and render & cladding joints, and people most often call us about weathered mastic that no longer stretches and sealant that has lost its bond to the brick or render.
Around Camberley, outside jobs take in garage door frames, porches, gutters and trims as well as walls. Each joint between different materials moves in its own way, so the sealant has to cope with that.
Every job is covered by a 12-month guarantee.

DIY versus a professional finish
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Some sealant jobs are within reach of a careful DIYer, 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.
Walls and rooflines in Camberley
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.
Homes close to Church of St Paul include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain. Schools such as Prior Heath Infant School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.

Aftercare tips
After the cure time, these simple habits help:
- Keep water from gutters off the wall
- Check the sealant is paintable before painting near it
- Keep movement joints as flexible joints, not mortar
- Point out the joints to other trades
Keep pressure washers away from the sealant. A strong jet can damage the edges of the bead over time.
Act while the splits are small. At that stage it’s a simple cut out and reseal with no damage behind it to deal with.
Work for landlords, hotels and businesses
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
We also work for property managers and facilities teams in Camberley and across Surrey. We can quote a run of properties together.
Why deal with it now?
It often makes sense to reseal all the failing joints on an elevation together. They’ve weathered the same way, and access only has to be arranged once. Black mould and gaps in sealant don’t fix themselves, and in a busy home in Camberley they get worse with every use. Now is the easy time to put it right.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs. Ask us for a quote and we will explain what it covers.
What you get with us
- Full insurance on every job
- Old sealant always removed completely
- Sanitary silicone with an anti-fungal additive in wet areas

What else we do in Camberley
What we are called out for in Camberley
Sometimes a movement joint was filled with mortar or a rigid filler. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
The problems people normally mention when they call are:
- Plants rooting in failed movement joints
- Panel joints letting water in
- Rigid filler in a joint that should flex
- Weathered mastic that no longer stretches
Letting a property close to Camberley station? Then split movement joints are easy to miss on a rental until damp shows inside.
What your quote should include
- Whether VAT is included
- What happens if they find a problem under the old sealant
- Whether the sealant suits the joint
- How the surfaces are prepared before sealing
Camberley: your questions answered
Is there a guarantee on external mastic in Camberley?
All our work, in Camberley and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
Do you cover Camberley for external mastic?
Yes, Camberley is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or drop us an email and let us know what needs doing, and we’ll give you a clear quote.
Will the new joint stand out?
Exterior sealants are made in a range of colours, from greys and browns to whites and stone shades. We choose the closest to your brick or render.
Do I need to be at home?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
Do you remove the old sealant?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Will it make a mess?
Tidy work is part of the job. Nearby surfaces are protected, and we clear up when we’re done.
Why do you put foam in the joint first?
We fit closed-cell backing rod wherever the joint depth needs controlling. It sets the sealant depth and prevents three-sided bonding, so the joint can move.
How long will you be here?
A typical job takes anything from a few hours to several days, depending on the building. We’ll confirm how long when we quote.
How the visit works
We keep the work tidy and contained to the area we’re working on, so you can carry on as normal. The job usually takes a few hours for a handful of joints, longer for a whole elevation. In Camberley, parking is rarely complicated, though it helps to know about driveways or restrictions, and let us know if the work is upstairs, in a flat or up high outside.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Plan for the work area to be out of bounds to pets and children
- Try not to wet indoor joints just before the visit
