External mastic in Purfleet-on-Thames
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product. We’re often asked to deal with rain getting behind render or cladding at a joint and gaps where render, brick and frames meet, across render & cladding joints, joints between brick and frames and copings & trims.
Outbuildings, garages and conservatories around homes in places like Purfleet-on-Thames add more joints to look after. Leaks usually start at a gutter end, a garage door frame or where an extension meets the house.
You are covered for a year from the day we finish. If there’s a problem with it, please phone 0345 464 0079 or email us.

Your questions about external mastic in Purfleet-on-Thames
I let a flat near Purfleet station. Can you help?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear price.
Do you cover Purfleet-on-Thames for external mastic?
Yes. Our work covers London and the South East, and Purfleet-on-Thames is part of that. You can ring 0345 464 0079 or email us and tell us what needs doing.
Do you hold any approvals?
Yes. We’re an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
Do you work for hotels and businesses?
Yes, regularly. We can plan bigger jobs in stages to suit the site.
Is it OK to seal over old sealant?
No. We remove every bit of old sealant first, so the new sealant bonds properly.
Where are you based?
We’re based in Crawley, and we cover South East England, London and all of Scotland.
How do you reach high-level joints?
It depends on the building. We work on joints that can be reached safely. Tell us about the building and we’ll confirm what access is needed.
Can you seal joints between render and window frames?
Yes. Materials like render, brick, metal and uPVC all move differently, so the joint between them must be flexible. We choose one that suits both surfaces.

DIY sealant or a professional job?
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
When something else is needed
In fairness, there are a few things sealant will not fix:
- Adding movement joints to masonry that has none
- Subsidence or other structural problems
- Cracking across the wall rather than at a joint
Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly.

How we quote for external mastic

- Any working-time requirements on site
- Mould in or behind the old joints
- Which sealant suits the joint
Combining jobs into one visit normally makes better use of the time than several visits. You will get one clear quote for the whole job.
Helping us quote
To make quoting easier, let us know:
- Photos by email, if that’s easy
- How we’d reach the joints
- Whether it’s a home or a business
- What’s wrong with the joints now

Do you need external mastic in Purfleet-on-Thames?
Many joints fail because they were sealed too deep or with nothing behind them. If the sealant sticks to the back as well as the sides, it can’t stretch and tears as soon as the joint widens.
It’s worth asking for a quote if you see:
- Water getting into walls through failed joints
- Movement joints with cracked, split or missing sealant
- Joints where the bead has come unstuck
- Failed sealant between panels on a façade
If you look after a building such as Purfleet Primary Academy, larger buildings have long runs of movement joint that eventually need resealing.
What your quote should include
- Whether they’re fully insured
- The length of the guarantee
- Is the old sealant removed completely?
- How the colour is chosen
Why it’s worth doing now in Purfleet-on-Thames
A failed movement joint lets water into the wall, behind render and cladding. Resealing early keeps the job to the joint itself, rather than the wall around it. Around Purfleet-on-Thames, water from a failed joint in an older home can soak into timber and plaster, and that is a much bigger job than renewing the sealant.
We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or drop us an email.

How it works
You do not need to clear the whole room or building before we come, only the area right around the joints. Everything nearby is protected, and the work takes a few hours to a few days, depending on the length of joint and the access for a typical job. In a smaller place like Purfleet-on-Thames, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- First we look over the joints with you, agree which to renew and talk through access.
- We cut out the failed sealant and rake out any dirt or growth.
- The joint faces are cleaned and primed where the sealant needs it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Getting ready for the visit
- Mention any parking rules near the property
- For business premises, tell us about site rules or sign-in
- Try not to wet indoor joints just before the visit

Advice
Aftercare tips
No joint lasts for ever, but care makes a real difference. Our tips:
- Walk round the building once a year and look at the joints
- Fix overflowing gutters above sealed joints
- Have failed joints looked at early
- Point out the joints to other trades
Have a quick look at the joints each spring. Splits, gaps at the edges or plants in the joint are early warning signs.
Leave a failed movement joint and water keeps getting into the wall. That can lead to damp patches, staining and frost damage, all bigger jobs than a reseal.
Outside joints around Purfleet-on-Thames
With historic houses such as Rainham Hall (about 3.1 miles north-west) nearby, there’s older building stock in the area around Purfleet-on-Thames as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Homes close to St Stephen's Church include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain. Letting a property close to Purfleet station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.
