About our external mastic in Parkgate
Low-level joints can normally be done from the ground. Where joints are higher up, tell us about the building when you get in touch and we will confirm what’s needed to reach them safely. We are often asked to deal with rain getting behind render or cladding at a joint and rigid filler in a joint that should flex, on copings & trims, render & cladding joints and joints between brick and frames.
Outside joints can only be sealed when they’re dry, so work in Parkgate is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
Big or small, it’s backed by our one-year guarantee.

How it works
The work is kept neat and contained to the area we are working on. The job generally takes a few hours for a handful of joints, longer for a whole elevation, and we explain the cure time before we leave. In a small place like Parkgate, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by checking each joint, agreeing the ones to redo and how we will reach them.
- The old mastic and anything lodged in the joint is removed.
- Both sides are cleaned back to sound material and primed if needed.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
How to prepare
- For business premises, tell us about site rules or sign-in
- Plan for the work area to be out of bounds to pets and children
- Let us know about parking restrictions

Advice
Can I do it myself?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.

FAQs for Parkgate
Is Parkgate in your area for external mastic?
Yes, Parkgate is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or drop us an email and tell us what needs doing.
Will you come out to Parkgate?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
How long before the joint can be used?
Many sealants skin over quickly but take longer to cure fully. We’ll tell you how long to leave the joint.
Do you have insurance?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Will you leave a mess?
We keep the work tidy. We protect what’s around the joints, and the area is left clean when we finish.
Why do you put foam in the joint first?
We fit closed-cell backing rod wherever the joint depth needs controlling. It sets the sealant depth and prevents three-sided bonding.
Which products do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we’ll explain our choice.
How often do external joints need resealing?
There’s no fixed answer: joints on exposed walls or with a lot of movement age sooner. A yearly look will tell you when they need doing. Our work comes with a 12-month guarantee.
When to call us in Parkgate
A lot of failed joints come down to preparation: dusty or wet faces, no primer where one was needed, or old sealant left in. The sealant never bonds properly.
Any of these means the joints need attention:
- Movement joints with cracked, split or missing sealant
- Panel joints letting water in
- Hard, crazed mastic that has stopped moving
- Sealant that has lost its bond to the brick or render
Letting a property close to Holmwood station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
Leave it or put it right?
Sealing over the top of old mastic does not hold for long. The new layer can’t bond properly to old, weathered material, so we always take the old sealant out. Older cottages and farmhouses around Parkgate can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
We do not show prices on the website, because each job is priced on what it involves. For a quick quote, please ring 0345 464 0079 or drop us an email.

Surface by surface
Render joints
Render has movement joints and stop beads that need sealing. They’re resealed in a sealant that suits the render.
Joints between dissimilar materials
Where a frame or panel meets masonry, water often finds a way in. The old joint is removed and a sealant that bonds to both sides goes in.
Walls and rooflines in Parkgate
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
