Leave it or put it right?
An open joint keeps letting water into the wall with every downpour. In cold weather, frost can damage wet brick and render, so the problem grows beyond the joint itself. Older cottages and farmhouses around Rivenhall End can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
The cost reflects the work involved, not guesswork. That’s why we ask about the job first and give you a clear quote before any work starts.

Will you come out to Rivenhall End?
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.
Will you leave a mess?
We keep the work tidy. We protect what’s around the joints, and the area is left clean when we finish.
Can you seal joints between render and window frames?
Yes. Joints between dissimilar materials are a big part of external work. We use a flexible sealant suited to both surfaces with primer where required.
Does someone need to be in?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you don’t need to watch us work.
Do you remove the old sealant?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.

Can you quote for more than one area?
Yes. Tell us about everything you’d like done.

When to call us in Rivenhall End
If plants are growing out of a joint, the sealant has generally failed or was never there. Dirt and roots then trap moisture in the joint and make things worse.
Keep an eye out for any of the following:
- Joints where the bead has come unstuck
- Weathered mastic that no longer stretches
- Damp patches traced to an open external joint
- Leaking joints around cladding and façade panels
Homes close to Church of St Mary and All Saints include some older properties, and the joints between older walls, newer extensions and the roofline need a sealant that can move.
What your quote should include
- Whether they seal over old material or remove it
- How the surfaces are prepared before sealing
- Who turns up on the day
- Which sealant they’ll use, and why

Letting a property close to Witham station? Then split movement joints are easy to miss on a rental until damp shows inside. Schools such as Rivenhall Church of England Primary School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.

What we cannot put right
New sealant cannot fix everything, and we will tell you before any work starts. It will not solve:
- Damp that is not coming from the joint
- Cracks in the bricks or render themselves, away from the joints
- Structural movement, which needs a surveyor or engineer

DIY versus a professional finish
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
How it works
There is not much for you to do on the day. Point us to the joints and we will get on with it. The work itself takes a few hours to a few days, depending on the length of joint and the access. Somewhere like Rivenhall End needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
Getting ready for the visit
- Mention any tricky access
- On commercial sites, let us know about site rules
- Keep children and pets away from the work area

Different materials may need different primers. Both surfaces are cleaned and primed as the product requires.

Jobs vary more than people expect. What affects the quote:
- How easy the joints are to reach
- How much old sealant there is and how hard it is to remove
- Working hours on commercial sites
- The number and length of the joints
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you’re unsure, ring 0345 464 0079 or email us and we will give you an honest view and a quote.
