External & façade joints in Woolhampton, West Berkshire
Problem with your movement joints in Woolhampton? We remove the old material, prepare the joints and seal them properly, with a one-year guarantee.
- Damp patches traced to an open external joint
- Sealant pulling away from one side of the joint
- Movement joints filled with mortar instead of sealant
When to call us in Woolhampton
Joints sealed without backing rod, or far too deep, rarely last. Sealant bonded to three sides has nowhere to go and tears as soon as the joint widens.
Common reasons people contact us are:
- Leaking joints around cladding and façade panels
- Sealant pulling away from one side of the joint
- Rigid filler in a joint that should flex
- Damp patches traced to an open external joint
Managing a site like Woolhampton C.E. Primary School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
What your quote should include
- Are they insured?
- Which sealant they’ll use, and why
- What happens if the job turns out different
- The length of the guarantee
External mastic in Woolhampton, done properly
A movement joint is a deliberate break that lets a wall expand and contract. Its sealant has to flex with the building, season after season, so once it splits or hardens, the joint stops working and water gets in. We work on façade panels, copings & trims and render & cladding joints, and the jobs we see most are gaps where render, brick and frames meet and joints where the bead has come unstuck.
Outside joints can only be sealed when they’re dry, so work in Woolhampton is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
Every job comes with a 12-month guarantee, wherever you are in West Berkshire.

What sealant work cannot fix
New sealant cannot fix everything, and we will tell you before work begins. It will not solve:
- Loose or hollow render, which needs re-rendering
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Cracking across the wall rather than at a joint
If you are not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer.

For landlords and businesses
Letting agents often deal with us directly. Tell us the address, the job and how access works and we will quote.
From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
How it works
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, do the work and clear up. Most jobs take a few hours to a few days, depending on the length of joint and the access. In a small place like Woolhampton, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by checking each joint, agreeing the ones to redo and how we will reach them.
- We cut out the failed sealant and rake out any dirt or growth.
- Both sides are cleaned back to sound material and primed if needed.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Before we arrive
- Tell us about any water getting in
- Keep pets and children clear of the area while we work
- For indoor joints, keep the area dry beforehand if you can

Common questions in Woolhampton
Is Woolhampton within the area you cover?
Yes. Woolhampton is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
I let a flat near Midgham station. Can you help?
Yes, landlords and agents are among the people we work for. You can call 0345 464 0079 or send us an email with the details for a clear quote.
Can you seal over the old sealant?
No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.
How long will you be here?
It depends on the size of the job, but most jobs take anything from a few hours to several days, depending on the building. We’ll give you a better idea when we quote.
Do you guarantee your work?
Yes. Every job comes with a one-year guarantee.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Do you have insurance?
Yes. We’re fully insured, and we can confirm the details when we quote.
What do you put in the joint?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Wash walls gently around the sealant
- Clear growth from the base of walls and joints
- Leave the joints unpainted unless we have said otherwise
- Tell anyone working on the walls about the movement joints
Don’t let soil, plants or ivy build up against the new joints. Anything that holds water against the joint wears it out sooner.
If you can see gaps, plants or bare sections in a joint, have it checked. Early work is quicker and leaves a better finish.
What affects the cost of external mastic
Jobs vary more than people expect. What affects the quote:
- The type of sealant required
- Whether there’s mould to deal with
- Working hours on commercial sites
- How many rooms, windows or areas are involved
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
Helping us quote
Before you ask for a quote, have a think about:
- Any previous sealing or DIY work
- Where the property is
- Pictures of the joints, sent by email
- Any access issues, like height or stairs

Different surfaces, different methods
Cladding and façade panels
Cladding and façade panels are usually separated by sealed joints. Each joint gets a sealant that suits the panel and its movement.
Render joints
Render has movement joints and stop beads that need sealing. We reseal them with a flexible exterior sealant that suits the render colour.
External mastic in Woolhampton: local notes
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Homes close to Church of St Peter include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain. For landlords with property near Midgham station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.
