About our external mastic in Painters Ash
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. The colour is chosen to suit the brick or render so the joint doesn’t stand out. Common call-outs are for moss and dirt in joints with no sealant left and rain getting behind render or cladding at a joint, across copings & trims, render & cladding joints and façade panels.
In a smaller place like Painters Ash, some homes face open ground, so exposed walls and rooflines take more wind-driven rain. That is where gutter joints and wall joints tend to fail first.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Outside joints around Painters Ash
Painters Ash is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Historic houses like Cobham College (about 3.6 miles south-east) are a reminder that the area around Painters Ash has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
For site and facilities teams at buildings such as Painters Ash Primary School, larger buildings have long runs of movement joint that eventually need resealing. For an older house near a landmark such as Church of All Saints, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

DIY versus a professional finish
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
A DIY attempt does not rule out a professional job. We cut it out and start again.
For landlords and businesses
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we will quote.
In hotels, rooms out of use cost money, so the work can be planned room by room. We have worked in hotels as well as homes and businesses.
What happens on the day
There isn’t much for you to do on the day. Show us the job and we’ll take it from there. The work itself takes a few hours to a few days, depending on the length of joint and the access, including the tidy-up. In a smaller place like Painters Ash, 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.
- We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
- Old sealant and any debris are cut and raked out.
- The joint faces are cleaned and primed where the sealant needs it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.

How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Fix overflowing gutters above sealed joints
- Ask before painting over external sealant
- Avoid pressure-washing directly into sealant joints
- Show decorators and builders where the movement joints are
Make sure anyone working on the wall later knows where the movement joints are. They should be kept open and resealed, not filled.
Once a joint cannot move, the wall finds another way, often as cracks near the joint. Catch it early and you reduce the risk.
Do you need external mastic in Painters Ash?
UV, rain and frost all age exterior sealant. In time it goes hard, crazes on the surface and stops stretching, so the joint eventually tears or comes away from one side.
Common reasons people contact us include:
- Gaps where render, brick and frames meet
- Weeds or debris growing in open joints
- Old sealant gone brittle and cracked
- Water getting into walls through failed joints
For landlords with property near Ebbsfleet International station, split movement joints are easy to miss on a rental until damp shows inside.

Painters Ash: your questions answered
Can you help a landlord with a rental near Ebbsfleet International station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
Is Painters Ash within the area you cover?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Is there any odour?
It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.
What information do you need?
A short description and the location, plus pictures if you have them. If we need more, we’ll ask.
Will you leave a mess?
Tidy work is part of the job. Nearby surfaces are protected, and we clear up when we are done.
When is the sealant fully cured?
Many sealants skin over quickly but take longer to cure fully. We will tell you how long to leave the joint.
Is it OK to fill a movement joint with cement?
No. Rigid materials cannot move with the wall. Where a joint has been mortared, it can often be raked out and sealed properly.
Why do you put foam in the joint first?
Backing rod controls the sealant depth and keeps it off the back of the joint. That way it bonds to the two sides only and can stretch.
When it isn’t the sealant
Some problems need a builder, plumber or other trade rather than us:
- Loose or hollow render, which needs re-rendering
- Cracking across the wall rather than at a joint
- Rising or penetrating damp from elsewhere in the wall
If in doubt, ring 0345 464 0079 or send us an email and we’ll say what we think before you book.
Joints and surfaces we work on

Why it’s worth doing now in Painters Ash
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That protects surfaces like brick, render and concrete. Too stiff a sealant can pull at the edges and break them. In a smaller place like Painters Ash, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
