External mastic in Newington
Ground-floor and low-level joints are straightforward to reach. For joints higher up, give us some details of the building and we will confirm what’s needed to reach them safely. Typical jobs include movement joints filled with mortar instead of sealant and gaps where render, brick and frames meet, on copings & trims, brickwork movement joints and render & cladding joints.
External sealant needs dry, clean surfaces, so work around Newington is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.

What happens on the day
There’s no need to move everything out, just the space around the work. We protect the rest, and the job takes anything from a few hours to several days, depending on the building for a typical job. In a small place like Newington, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- Joint faces are cleaned back and primed if the sealant needs it.

- The exterior sealant is applied, tooled and checked along its length.

Common questions in Newington
Do you work for landlords with property near Folkestone West station?
Yes, we work for landlords and letting agents. Just call 0345 464 0079 or email us and tell us about the property, and we will give you a clear price.
Is external mastic in a coastal place like Newington any different?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
How do I get a quote for external mastic in Newington?
Size, access and the old material all affect the cost. Call for a quick quote.
Does someone need to be in?
Access is agreed with you when the job is booked. Indoors, that usually means someone at home.
Where is Mr Mastic based?
We work from Crawley. We cover Newington and the rest of Kent, along with the rest of our area.
Can you seal joints between render and window frames?
Yes. Where different materials meet is one of the most common joints we seal. We use a flexible sealant suited to both surfaces with primer where required.
Should I point up the gap in my brickwork?
No. Rigid materials can’t move with the wall, so the joint stops doing its job. Where a joint has been mortared, it can often be raked out and sealed properly.
Why is there a gap in my brick wall?
Walls move with heat, cold and moisture, so long walls have planned gaps to take that movement. The gap is sealed with a flexible sealant over backing rod.
Signs you need external mastic in Newington
Poor preparation causes many early failures: dusty or wet faces, no primer where one was needed, or old sealant left in. The sealant never bonds properly.
Most people get in touch after spotting something like this:
- Hard, crazed mastic that has stopped moving
- Sealant pulling away from one side of the joint
- Movement joints with cracked, split or missing sealant
- Rigid filler in a joint that should flex
Rented homes near Folkestone West station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.
Questions to ask before you book
- Is VAT in the price?
- Who turns up on the day
- Are they insured?
- Which sealant they’ll use, and why
Other services in Newington
Different surfaces, different methods
Render joints
The face of render can be soft, so a low-modulus sealant is kinder to the joint edges. We prime where the product needs it.
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. That movement goes into the joint, so its sealant has to stay flexible.
What affects the cost of external mastic
The quote reflects the job in front of us. We look at:
- Access and height
- The old material and how stubborn it is
- Mould in or behind the old joints
- The product the joint needs
What you pay reflects the work, not guesswork. That’s why we ask about the job first and agree the price before starting.
What we need to know
Photos by email are helpful but not essential. Try to tell us:
- Pictures of the joints, sent by email

Walls and rooflines in Newington
Newington 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 Acrise Place (about 3.2 miles north) are a reminder that the area around Newington has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
For an older house near a landmark such as Church of St Nicholas, an extension built onto an older house moves differently, and the joint between them takes the strain.

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, so just mention it when you contact us.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
How to look after the new joints
Looking after new joints is easy:
- Point out the joints to other trades
- Walk round the building once a year and look at the joints
- Wash walls gently around the sealant
- Clear growth from the base of walls and joints
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.
Leave a failed movement joint and water keeps getting into the wall. That can lead to damp patches, staining and frost damage which cost more to put right than the joint.
