External Mastic in Frostlane
Specialist external mastic for Frostlane: careful preparation, the right product and tidy work. Call for a quick quote.
- Panel joints letting water in
- Damp patches traced to an open external joint
- Weathered mastic that no longer stretches
Keeping the joints in good condition
Looking after new joints is easy, and it makes a real difference:
- Check external joints each spring
- Deal with leaking gutters that soak the joints below
- Make sure movement joints aren’t pointed over
- Keep soil, plants and ivy away from the joints
Only paint over the joint if we’ve confirmed the sealant can take paint. Paint can crack on a flexible joint and spoil the finish.
If you can see gaps, plants or bare sections in a joint, have it checked. Early work is quicker and leaves a better finish.
External mastic in Frostlane
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible exterior sealant takes up that movement where mortar or filler would crack. We work on façade panels, render & cladding joints and joints between brick and frames, and the jobs we see most are joints pointed up with cement by mistake and joints where the bead has come unstuck.
Around Frostlane, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or email us.

Landlords, agents and businesses in Frostlane
Letting agents often deal with us directly. Tell us the address, the job and how access works and we will quote.
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
DIY versus a professional finish
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
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.
What we do, step by step
All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. 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. In a small place like Frostlane, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- 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.
Before we arrive
- Let us know about earlier repairs to the joints
- Let us know if you’ve seen damp or leaks
- For business premises, tell us about site rules or sign-in

Advice

What we are called out for in Frostlane
Every building moves. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. All of that ends up in the joint sealant.
Keep an eye out for any of the following:
- Movement joints filled with mortar instead of sealant
- Movement joints with cracked, split or missing sealant
- Joints where the bead has come unstuck
- Rain getting behind render or cladding at a joint
If you live in an older home near St Anne, an extension built onto an older house moves differently, and the joint between them takes the strain.
What to look for in a quote
- What the quote includes, VAT included or not
- How the joint is cleaned and prepared
- Whether they seal over old material or remove it
- Whether they’re fully insured
Outside joints around Frostlane
Frostlane is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. Historic houses like Medieval Merchant's House (about 3.1 miles north) are a reminder that the area around Frostlane has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
For landlords with property near Netley station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. If you look after a building such as Waterside Primary School, its movement joints, gutters and trims need looking after like any other building’s.

Questions from Frostlane
Can you help a landlord with a rental near Netley station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear price.
Does the coastal weather in Frostlane affect outside sealant?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. Walls facing the sea are generally the first to need attention.
Is there any odour?
Sometimes, a little. It fades as the sealant cures.
Do you have insurance?
Yes. We are fully insured for domestic and commercial work.
Is it messy?
Tidy work is part of the job. We protect what’s around the joints, and the area is left clean when we finish.
Is it OK to seal over old sealant?
No, and we never do. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.
Are you an approved applicator?
Yes. We are approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
Can you do several jobs on one visit?
Yes. Several rooms, windows or areas can go on one quote.
Different surfaces, different methods
Copings and trims
Joints in copings, parapets and trims are exposed to the worst of the weather. Each is resealed with a weatherproof, flexible sealant.
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. Each joint gets a sealant that suits the panel and its movement.
What we cannot put right
New sealant can’t fix everything, and we’ll tell you before work begins. Sealant won’t put right:
- Render that’s blown, hollow or coming away
- Structural movement, which needs a surveyor or engineer
- Cracks in the bricks or render themselves, away from the joints
If you are not sure, just phone 0345 464 0079 or email us and we will give you a straight answer before you book.
