Common problems we fix in Maplescombe
Some movement joints have been pointed up with mortar, often by someone who didn’t know what it was for. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
Signs it’s time to call us include:
- Hard, crazed mastic that has stopped moving
- Sealant pulling away from one side of the joint
- Water getting into walls through failed joints
- Gaps where render, brick and frames meet
For landlords with property near Eynsford station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Surface by surface
Copings and trims
Metal and stone copings both move with temperature, so a flexible sealant suits them best.
Joints between dissimilar materials
Where a frame or panel meets masonry, water often finds a way in. We cut out the old sealant and reseal with a product suited to both surfaces.
What affects the quote in Maplescombe
You’ll get a clear quote before we start. It’s based on:
- When we can work, for business premises
- Mould in or behind the old joints
- Whether the work is at height
- Whether old sealant or filler has to be cut out
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, call 0345 464 0079 or send us an email and we will give you an honest view and a quote.

Common questions in Maplescombe
Will you come out to Maplescombe?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you cover Maplescombe for external mastic?
Yes. Our work covers London and the South East, and Maplescombe is part of that. You can phone 0345 464 0079 or drop us an email and tell us what needs doing, and we’ll give you a clear quote.
Are you an approved applicator?
Yes. We are an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
Can landlords and businesses book you?
Yes, we do. Domestic, commercial and hotel work are all part of what we do, and we are fully insured.
Do you use backing rod?
That is backing rod, a closed-cell foam. It stops the sealant going in too deep and bonding to three sides, which would stop it stretching.
How long will you be here?
It depends on the size of the job, but as a guide it takes anything from a few hours to several days, depending on the building. We will give you a better idea when we quote.
Can you seal joints between two different materials?
Yes. Joints between dissimilar materials are a big part of external work. We use a flexible sealant suited to both surfaces, primed where needed.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
How the visit works
The work is kept neat and contained to the joints we are treating, so you can get on with your day. The job normally takes a few hours for a handful of joints, longer for a whole elevation. In a small place like Maplescombe, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by walking round the building and agreeing the joints and the access.
- We cut out the old mastic and rake out anything in the joint.
- The faces are brushed clean and primed where the product requires it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
Getting ready for the visit
- Mention any sign-in or site rules at work premises
- Let us know about parking restrictions
- Let us know about earlier repairs to the joints
Getting a quote
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is.
Related advice
DIY versus a professional finish
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.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
What happens if it’s left?
Mortar or ordinary filler might look like a quick way to close an open joint, but it locks the joint solid. The wall then cracks somewhere else. A flexible sealant over backing rod is what the joint needs. Where a wall is exposed, as many are in small places like Maplescombe, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we’ll explain the quote if you ask.

What else we do in Maplescombe
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Don’t let climbing plants root in the sealant
- Wash walls gently around the sealant
- Fix overflowing gutters above sealed joints
- Walk round the building once a year and look at the joints
Give the sealant the cure time we tell you before anything rubs against it. Most exterior sealants skin fast but take longer to cure right through.
If you can see gaps, plants or bare sections in a joint, have it checked. Earlier resealing means a smaller job and a better result.
