How we handle external mastic in Enfield Wash
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Some surfaces need a primer before sealing and we use one wherever it does. If you are dealing with movement joints filled with mortar instead of sealant and plants rooting in failed movement joints, we can help, on façade panels, brickwork movement joints and joints between brick and frames alike.
In a smaller place like Enfield Wash, some homes face open ground, and walls and rooflines facing the weather take the worst of it. That’s where gutter joints and wall joints tend to fail first.
Every job comes with our one-year guarantee.

Walls and rooflines in Enfield Wash
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Forty Hall (about 1.3 miles west) are a reminder that the area around Enfield Wash has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
For landlords with property near Turkey Street station, outside joints that have cracked can let damp into a rental, so check them between lets. If you look after a building such as Eastfield Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Looking after it afterwards
Aftercare is simple, and it makes a real difference:
- Show decorators and builders where the movement joints are
- Clear growth from the base of walls and joints
- Look over the joints every year, ideally after winter
- Keep water from gutters off the wall
Follow the cure time we give you before the joint is knocked or disturbed. Most exterior sealants skin fast but take longer to cure right through.
Act while the splits are small. At that stage it’s a simple cut out and reseal before water has had years to get in.
Work for landlords, hotels and businesses
For anyone letting property in or around Enfield Wash, several properties can go on one quote. Just tell us the addresses and what each one needs.
We also work for property managers and facilities teams. We can quote a run of properties together, and we’re fully insured.
Can I do it myself?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
How the job changes by surface
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. Each joint gets a sealant that suits the panel and its movement.
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.
What happens on the day
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes anything from a few hours to several days, depending on the building and we leave things clean and tidy. Parking around Enfield Wash is usually easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- 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.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Preparing for the visit
- Let us know if you’ve seen damp or leaks
- Tell us about any previous sealing or DIY attempts
- Mention any tricky access

Quotes for external mastic in Enfield Wash
Every job gets its own quote. These are the things that affect it:
- Whether old sealant or filler has to be cut out
- The amount of work
- The number of rooms or windows
- Which sealant suits the joint
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.
Helping us quote
Photos by email are helpful but not essential. Try to tell us:
- Photos by email, if that is easy
- Access, such as stairs, a lift or height
- The address or postcode of the job
- Whether it has been sealed before
We do not publish a price list, because every job is different. Instead, your job gets its own clear quote. To arrange one, ring 0345 464 0079 or email us.
Common problems we fix in Enfield Wash
Weeds, moss and debris in a joint are a sign the sealant has gone. Roots and dirt hold water against the wall.
Any of these means the joints need attention:
- Joints pointed up with cement by mistake
- Failed sealant between panels on a façade
- Cracked joints where brick meets render or frames
- Damp patches traced to an open external joint
For an older house near a landmark such as St George's Church, an extension built onto an older house moves differently, and the joint between them takes the strain.
Questions to ask before you book
- What the quote includes, VAT included or not
- Is the old sealant removed completely?
- How the joint is cleaned and prepared
- Whether they’re fully insured
Questions from Enfield Wash
Is Enfield Wash within the area you cover?
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.
Is Enfield Wash in your area for external mastic?
Yes. We work across London and the South East, and Enfield Wash is part of that. You can phone 0345 464 0079 or drop us an email and tell us what needs doing.
Can landlords and businesses book you?
Yes, we do. Domestic, commercial and hotel work are all part of what we do, and we’re fully insured.
How long before the joint can be used?
Different products cure at different speeds, so follow the cure time we give you when we finish.
Is there a guarantee?
Yes. All our work carries a one-year guarantee.
Can a movement joint be filled with mortar?
No. Rigid materials cannot move with the wall. If it has already been filled, we can normally cut it out and reseal it.
Do the sealants smell?
Some sealants have a smell while they cure. Ventilation helps.
Can you seal over the old sealant?
No, it will not last. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
