What external mastic looks like in Wells-in-the-Field
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Schools such as Whitchurch Church of England Primary School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s. For landlords with property near Whitchurch (Hampshire) station, split movement joints are easy to miss on a rental until damp shows inside. If you live in an older home near St Nicholas' Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

External mastic in Wells-in-the-Field
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. We pick a colour that sits well with the wall so the joint doesn’t stand out. Typical jobs include sealant pulling away from one side of the joint and gaps where render, brick and frames meet, on joints between brick and frames, brickwork movement joints and concrete & block.
Outside joints can only be sealed when they’re dry, so work in Wells-in-the-Field is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
A one-year guarantee comes with the work, just as it does everywhere we cover.

What we can’t put right

- Adding movement joints to masonry that has none
- Cracks in the bricks or render themselves, away from the joints
- Failed render or damaged cladding panels
If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think.

What affects the cost of external mastic
Every job gets its own quote. This is what makes a difference:
- Whether there’s mould to deal with
- The number and length of the joints
- Which sealant suits the joint
- The number of rooms or windows
No two jobs are quite the same, so we quote each one individually. 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 we need to know
Before you ask for a quote, have a think about:
- What’s wrong with the joints now
- The type of property
- How many joints, rooms or windows are involved
- Pictures of the joints, sent by email
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will explain how we’d tackle it. Whenever you’re ready, call 0345 464 0079 or send us an email.
Surface by surface
Copings and trims
Joints in copings, parapets and trims are exposed to the worst of the weather. We reseal them with an exterior sealant suited to the material.
Concrete and blockwork
Wide joints in concrete need the depth controlling carefully. Backing rod sized to the joint sets it.

How it works
Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for a handful of joints, longer for a whole elevation. For a village or hamlet like Wells-in-the-Field, the journey is planned in advance: 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.
- 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.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us if parking is tricky
- Keep pets and children clear of the area while we work

Leave it or put it right?
It often makes sense to reseal all the failing joints on an elevation together. They’ve weathered the same way and it means sorting access once. Older cottages and farmhouses around Wells-in-the-Field can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Doing several joints on one visit normally makes better use of the time than several visits. We’ll send you a clear quote for the lot.
What you get with us
- Quality sealants from Arbo and Everbuild
- You choose the colour before work begins
- Sealant colour chosen to suit
- Sanitary silicone with an anti-fungal additive in wet areas

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 thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
Work for landlords, hotels and businesses
Housing providers, facilities teams and property managers book us too. Several sites can be quoted together, and we are fully insured.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can be quoted together.
