External mastic in Hungerford, done properly
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. We work on concrete & block, façade panels and copings & trims, and people most often call us about leaking joints around cladding and façade panels and hard, crazed mastic that has stopped moving.
External sealant needs dry, clean surfaces, so work around Hungerford is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

Common problems we fix in Hungerford
Many joints fail because they were sealed too deep or with nothing behind them. If the sealant sticks to the back as well as the sides, it cannot stretch and tears as soon as the joint widens.
Most people get in touch when they notice something like this:
- Joints where the bead has come unstuck
- Rigid filler in a joint that should flex
- Gaps where render, brick and frames meet
- Damp patches traced to an open external joint
For site and facilities teams at buildings such as Hyde Church of England Primary School, larger buildings have long runs of movement joint that eventually need resealing.

FAQs for Hungerford
Is Hungerford in your area for external mastic?
Yes, Hungerford is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or send us an email and let us know what needs doing, and we will give you a clear price.
Is external mastic in Hungerford guaranteed?
All our work, in Hungerford and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
Where are you based?
Mr Mastic is based in Crawley. We cover Hungerford and the rest of Hampshire, along with the rest of our area.
Is it worth trying it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
Are you fully insured?
Yes. Full insurance covers our work.
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 pick the one that suits your wall best.
When will the joints need doing again?
That depends on the wall, the weather and the movement. Signs to watch for are cracking, hardening and gaps at the edges.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Why it’s worth doing now in Hungerford
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That matters on brick, render and concrete, which can be weaker at the face. A stiffer product can damage the joint edge as it fails. Where a wall is exposed, as many are in small places like Hungerford, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
The cost depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before any work starts, so you know where you stand.

Walls and rooflines in Hungerford
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Breamore House (about 4.3 miles north) are a reminder that the area around Hungerford 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.
In the older streets around Church of the Holy Ascension, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

What the job involves on each surface
Concrete and blockwork
Concrete faces can be dusty and porous, so preparation is key. A primer goes on where the product requires one before the bead.
Joints between dissimilar materials
Joints where frames, sills or panels meet the wall are common leak points. The old joint is removed and a sealant that bonds to both sides goes in.
