Walls and rooflines in Woodley
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
In the older streets around United Reformed Church, the joints between older walls, newer extensions and the roofline need a sealant that can move. For site and facilities teams at buildings such as Rivermead Primary School, larger buildings have long runs of movement joint that eventually need resealing.

External mastic in Woodley
Low-level joints can normally be done from the ground. For joints higher up, give us some details of the building and we’ll confirm what access is needed. We work on joints between brick and frames, render & cladding joints and copings & trims, and the jobs we see most are hard, crazed mastic that has stopped moving and movement joints filled with mortar instead of sealant.
Plenty of homes in a town like Woodley have been extended, and the joint where new wall meets old is a classic place for water to get in. Sealing it properly means the right joint depth and a flexible sealant, not a quick bead.
All of our work is guaranteed for twelve months, in Woodley and everywhere else we cover.

Work for landlords, hotels and businesses
We work for letting agents and landlords as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order.
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
What we are called out for in Woodley
Joints sealed without backing rod, or far too deep, rarely last. If the sealant sticks to the back as well as the sides, it can’t stretch and rips as the joint opens.
The problems people normally mention when they call are:
- Gaps where render, brick and frames meet
- Water getting into walls through failed joints
- Moss and dirt in joints with no sealant left
- Joints where the bead has come unstuck
Rented homes near Winnersh Triangle station change hands often, and split movement joints are easy to miss on a rental until damp shows inside.
Before booking anyone
- What product goes in the joint
- Who does the work, and how experienced they are
- What guarantee comes with the work
- Whether they’re fully insured

Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it or an approved alternative. Send us any details you have about the façade.
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. That movement goes into the joint, so its sealant has to stay flexible.
Woodley: your questions answered
Can you help a landlord with a rental near Winnersh Triangle station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
Is Woodley in your area for external mastic?
Yes, Woodley is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or email us with a few details of the job.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done.
Do you have insurance?
Yes, we’re fully insured for domestic and commercial work.
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. The old sealant has to come out completely.
When is the sealant fully cured?
Most sealants are touch-dry well before they’re fully cured. We will tell you how long to leave the joint before we leave.
Will you leave a mess?
Tidy work is part of the job. Nearby surfaces are protected, and we clear up when we are done.
How do you reach high-level joints?
It depends on the height and the site. Low-level joints are straightforward; for higher ones, send details and we will confirm the access.
What affects the quote in Woodley
For a quick quote, just ask. What matters most is:
- Mould in or behind the old joints
- The number of rooms or windows
- The number and length of the joints
- Whether old sealant or filler has to be cut out
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Asking for a quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- What’s wrong with the joints now
- The type of property
- Pictures of the joints, sent by email
- How we’d reach the joints
There’s no standard price list. Instead, we give you a clear quote for your job. To arrange one, ring 0345 464 0079 or send us an email.
Why deal with it now?
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That matters on brick, render and concrete, which can be weaker at the face. Too stiff a sealant can pull at the edges and break them. In Woodley, as anywhere, most leaks start as a small gap in a joint, and they’re far easier to fix early.
The cost depends on the amount of work, how much old material has to come out and access to the work. You’ll have a clear quote before any work starts, so you know where you stand.
What you get with us
- Full insurance on every job
- Anti-fungal sanitary silicone in wet areas
- One-year guarantee on every job
- Approved under the ARBOMaster scheme

Should I try it myself first?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
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.
The process
The work is kept neat and contained to the area we are working on, so you can carry on as normal. Expect the work to take anything from a few hours to several days, depending on the building, and we tell you how long to leave it before we go. Parking in a town like Woodley is usually straightforward, but tell us if there’s a driveway or any restrictions, and mention if the work is upstairs, in a flat or high on the outside.
- 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.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can
- Mention any sign-in or site rules at work premises
- Mention any tricky access
