External & façade joints in Cove, Hampshire
Movement joints in Cove need attention? We remove the old material, prepare the joints and seal them properly.

- Leaking joints around cladding and façade panels
- Water getting into walls through failed joints
How we handle external mastic in Cove
On houses, flats and commercial buildings across Cove, we reseal joints in brickwork, render, cladding and façade panels. The preparation is the same whatever the wall: clean, sound faces and a controlled depth. We work on render & cladding joints, brickwork movement joints and joints between brick and frames, and common reasons people get in touch are joints with sealant missing in places and rigid filler in a joint that should flex.
Outbuildings, garages and conservatories around homes in places like Cove add more joints to look after. Leaks generally start at a gutter end, a garage door frame or where an extension meets the house.
Big or small, it’s backed by our one-year guarantee.

Common questions in Cove
Do you cover smaller places like Cove?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you do external mastic in Cove?
Yes. Our work covers London and the South East, and Cove is part of that. You can phone 0345 464 0079 or email us and let us know what needs doing.
Can I add another job to the visit?
Yes. Tell us about everything you’d like done and we will quote it together.
Does someone need to be in?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Will it make a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we are fully insured.
Will there be a smell?
Sometimes, a little. Any smell clears as the sealant cures, and ventilation helps.
When is the sealant fully cured?
Different products cure at different speeds, so follow the cure time we give you.
When something else is needed
We will not take on work that will not last, so these are the limits:
- Cracking across the wall rather than at a joint
- Adding movement joints to masonry that has none
- Failed render or damaged cladding panels
If in doubt, call 0345 464 0079 or drop us an email and we’ll say what we think before you book.

Housing providers, facilities teams and property managers book us too in Cove and across Hampshire. We can quote a run of properties together, and we’re fully insured for the work.
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we will give you a quote.
Why deal with it now?
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. Homes in smaller places like Cove can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
The cost depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before work begins, so you know where you stand.

- Colour picked to suit the job

DIY sealant or a professional job?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Outside joints around Cove
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For landlords with property near Fleet station, split movement joints are easy to miss on a rental until damp shows inside. Schools such as Parsonage Farm Nursery and Infant School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s. If you live in an older home near St John the Baptist, older walls, gutters and the joints where extensions meet them need a flexible sealant.

Surface by surface
Cladding and façade panels
If the façade has a specified sealant, that’s what we use or an approved alternative. Send us any details you have about the façade.
Concrete and blockwork
Concrete faces can be dusty and porous, so preparation is key. A primer goes on where the product requires one before the bead.

What affects the cost of external mastic
We don’t publish a price list. The quote depends on:
- Whether there’s mould to deal with
- The size of the job
- The product the joint needs
- The old material and how stubborn it is
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
What to tell us for a quote
There’s no need for technical detail. Just tell us:
- Any previous sealing or DIY work
- The rough size of the job
- Photos by email, if that is easy
- Any access issues, like height or stairs
For a quote, call 0345 464 0079 or send us an email and tell us where the job is and what the problem looks like. We will give you a clear quote before any work starts.
What we do, step by step
On the day, we start by going over the job with you. We protect the surfaces around the joints before any work begins. The work generally takes a few hours for a handful of joints, longer for a whole elevation. In a smaller place like Cove, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
How to prepare
- Try not to wet indoor joints just before the visit
- Let us know about earlier repairs to the joints
- Keep pets and children clear of the area while we work
