Walton: your questions answered
I let a flat near Aylesbury station. Can you help?
Yes. We work for landlords and agents as well as householders, and several properties can be quoted together. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we will give you a clear price.
Is Walton within the area you cover?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can you seal over the old sealant?
No, it won’t last. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Will it make a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Is there any odour?
It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Can you work on commercial sites?
Yes. We’ve worked for hotels, offices and other businesses and we’re fully insured.
Do you hold any approvals?
Yes. We’re approved under the ARBOMaster scheme.
How we handle external mastic in Walton
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant in a matching colour. We are often asked to deal with damp patches traced to an open external joint and leaking joints around cladding and façade panels, across façade panels, brickwork movement joints and render & cladding joints.
External sealant needs dry, clean surfaces, so work around Walton is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.
There’s a 12-month guarantee on every job, whatever its size.

When something else is needed
We will not take on work that will not last, so here’s what sealant cannot put right:
- Loose or hollow render, which needs re-rendering
- Cutting new joints into brickwork, which is building work rather than sealant work
- Cracked brickwork or render that needs a builder or plasterer
If in doubt, phone 0345 464 0079 or email us and we will say what we think before you book.
Joints and surfaces we work on
- Render & cladding joints
- Façade panels
- Copings & trims
- Brickwork movement joints
- Joints between brick and frames
- Concrete & block
Different surfaces, different methods
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.
Render joints
Cracks along render joints let water in behind the coat. Resealing the joints early keeps water out.
Landlords, agents and businesses in Walton
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we’ll give you a quote.
We work for landlords and letting agents as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
What happens if it’s left?
Water gets in through a failed movement joint and can run behind render or cladding. Dealing with it early keeps the repair to the joint, rather than the wall around it. In a small place like Walton, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.

Walls and rooflines in Walton
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Rented homes near Aylesbury station change hands often, and split movement joints are easy to miss on a rental until damp shows inside. Homes close to Holy Trinity include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain.

What we are called out for in Walton
A lot of failed joints come down to preparation: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The sealant never bonds properly.
Look out for these signs:
- Rain getting behind render or cladding at a joint
- Moss and dirt in joints with no sealant left
- Gaps where render, brick and frames meet
- Movement joints with cracked, split or missing sealant
If you look after a building such as Aylesbury High School, its movement joints, gutters and trims need looking after like any other building’s.
What your quote should include
- What happens if they find a problem under the old sealant
- Whether all the old sealant comes out first
- Whether VAT is included
- Whether the sealant suits the joint
Aftercare tips
So the new joints stay in good condition:
- Keep water from gutters off the wall
- Check the sealant is paintable before painting near it
- Never let anyone fill a movement joint with mortar
- Clear growth from the base of walls and joints
Look over the joints once a year, ideally after winter. Splits, gaps at the edges or plants in the joint are early warning signs.
Leave a failed movement joint and water keeps getting into the wall. Over time it can mean damp inside, stained render or frost-damaged brick.
What happens on the day
There’s no need to move everything out, only the area right around the joints. Everything nearby is protected, and the work takes anything from a few hours to several days, depending on the building for a typical job. In a small place like Walton, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- Old sealant and any debris are cut and raked out.
- Both sides are cleaned back to sound material and primed if needed.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Getting ready for the visit
