About our external mastic in Greenstead Green
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Porous or awkward surfaces are primed where the sealant needs it, and we do not skip that step. If you’re dealing with rigid filler in a joint that should flex and joints with sealant missing in places, we can put it right, on joints between brick and frames, concrete & block and brickwork movement joints alike.
Older homes in small places like Greenstead Green may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.
A 12-month guarantee comes as standard.

FAQs for Greenstead Green
Will you come out to Greenstead Green?
Yes, Greenstead Green is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you work for landlords with property near Chappel & Wakes Colne station?
Yes. We work for landlords and agents as well as householders. Just call 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear price.
What colours does the sealant come in?
We choose a sealant colour to suit the brick, stone or render. There’s a wide choice of exterior colours.
Do you seal joints where cladding meets other materials?
Yes. The old joint is removed, both surfaces cleaned and primed where needed, and a flexible sealant applied. The colour is chosen to suit.
How long will you be here?
Typically it takes a few hours to a few days, depending on the length of joint and the access. Larger jobs naturally take longer, and we’ll say how long yours will take.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us and we are fully insured.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Are you insured?
Yes, we’re fully insured for domestic and commercial work.
When something else is needed
New sealant cannot fix everything, and we’d rather say so up front. It will not solve:
- Walls that need new movement joints cut into them
- Rising or penetrating damp from elsewhere in the wall
- Subsidence or other structural problems
If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think.

When to call us in Greenstead Green
Buildings move more than people expect. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. All of that ends up in the joint sealant.
The problems people normally mention when they call are:
- Moss and dirt in joints with no sealant left
- Damp patches traced to an open external joint
- Joints pointed up with cement by mistake
- Joints where the bead has come unstuck
If you live in an older home near Parish Church of St James, older walls, gutters and the joints where extensions meet them need a flexible sealant.

The process
All our tools and materials come with us in the van. After a quick look at the joints together, the area is protected and the work begins. It normally takes anything from a few hours to several days, depending on the building. In a small place like Greenstead Green, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Getting ready for the visit
- Let us know about earlier repairs to the joints
- Plan for the work area to be out of bounds to pets and children
- Mention any tricky access

Advice
Quotes for external mastic in Greenstead Green
For a quick quote, just ask. The main things that affect it are:
- The old material and how stubborn it is
- Whether there’s mould to deal with
- The amount of work
- Access and height
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

For landlords and businesses
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
Mouldy or split sealant often shows up at the end of a tenancy. Several properties can go on one quote.
Keeping the joints in good condition
After the cure time, these simple habits help:
- Keep water from gutters off the wall
- Have failed joints looked at early
- Keep movement joints as flexible joints, not mortar
- Do not let climbing plants root in the sealant
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.
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.
Should I try it myself first?
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.
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.
