External Mastic in Reigate
We cover Reigate for sealing brickwork movement joints, render, cladding and façade joints. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.

External mastic for homes and businesses in Reigate
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Porous or awkward surfaces are primed where the sealant needs it. If you have weathered mastic that no longer stretches and plants rooting in failed movement joints, we can help, on brickwork movement joints, concrete & block and render & cladding joints alike.
Around Reigate, outside jobs take in garage door frames, porches, gutters and trims as well as walls. Where two materials meet, they move differently, and the sealant has to allow for it.
All our work comes with a one-year guarantee.

FAQs for Reigate
I let a flat near Reigate station. Can you help?
Yes, we work for letting agents and landlords. You can phone 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before we start.
Is Reigate in your area for external mastic?
Yes. Our work covers London and the South East, and Reigate is part of that. You can call 0345 464 0079 or drop us an email and tell us what needs doing, and we’ll give you a clear quote.
Are you insured?
Yes. We are fully insured, and we’ve been doing sealant work for more than 20 years.
When will the joints need doing again?
That varies with the weather the wall faces, how much it moves and the sealant used. Sealant is a maintenance item, so check the joints once a year and reseal when it splits.
Is it worth trying it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
How do you reach high-level joints?
It depends on the building. Where joints can be reached safely, we will do them. Tell us about the building and we’ll confirm what access is needed.
Where do you work from?
We are a Crawley-based firm. We work across South East England, London and Scotland.
What sealant do you use?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
What happens on the day
We bring everything the job needs with us, so there’s nothing for you to buy. After a quick look at the joints together, the area is protected and the work begins. Most jobs take anything from a few hours to several days, depending on the building. For a job in Reigate, we need access to where the work is and somewhere nearby to park. For outside work, let us know about side access, gates and any upper-floor joints.
- 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.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
Getting ready for the visit
- Let us know about earlier repairs to the joints
- Mention any tricky access
- Mention any sign-in or site rules at work premises

Advice
Outside joints around Reigate
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.
For landlords with property near Reigate station, outside joints that have cracked can let damp into a rental, so check them between lets. In the older streets around Church of St Mary Magdalene, older walls, gutters and the joints where extensions meet them need a flexible sealant.

Can I do it myself?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Common problems we fix in Reigate
If plants are growing out of a joint, the sealant has usually failed or was never there. Roots and dirt hold water against the wall and speed up the damage.
Look out for any of the following:
- Plants rooting in failed movement joints
- Joints where the bead has come unstuck
- Leaking joints around cladding and façade panels
- Gaps where render, brick and frames meet
For site and facilities teams at buildings such as Reigate Priory Community Junior School, larger buildings have long runs of movement joint that eventually need resealing.
Before booking anyone
- The length of the guarantee
- Whether they seal over old material or remove it
- Which colour the sealant will be
- Whether the sealant suits the joint
Work for landlords, hotels and businesses
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
Hotels need rooms back in use, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
How the job changes by surface
Concrete and blockwork
Wide joints in concrete need the depth controlling carefully. We size the backing rod to the gap and keep the sealant to the right depth.
Joints between dissimilar materials
Where a frame or panel meets masonry, water often finds a way in. The old joint is removed and a sealant that bonds to both sides goes in.
When something else is needed
A few problems are outside what sealant work can do:
- Cracks in the bricks or render themselves, away from the joints
- Movement that’s more than a sealant joint can take
- Rising or penetrating damp from elsewhere in the wall
If you’re not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer before you book.
What we seal
- Concrete & block
- Copings & trims
- Façade panels
- Joints between brick and frames
- Render & cladding joints
- Brickwork movement joints
Leave it or put it right?
Pointing a movement joint with mortar might seem a neat fix, but it locks the joint solid. The wall then cracks somewhere else. The correct repair is a flexible sealant with the right backing. In Reigate, as anywhere, most leaks start as a small gap in a joint, and they’re far easier to fix early.
The cost reflects the work involved, not guesswork. That’s why we ask a few questions first and give you a clear price before any work starts.
