What we do, step by step
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes a few hours to a few days, depending on the length of joint and the access. In a small place like Pilley, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, the joints are inspected and the access agreed.
- We cut out the old mastic and rake out anything in the joint.
- The faces are brushed clean and primed where the product requires it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
Before we arrive
- Mention any leaks or damp you’ve noticed
- Mention if the joints have been sealed before
- Mention any sign-in or site rules at work premises

External mastic for homes and businesses in Pilley
Getting the depth right is half the job. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, leaving it bonded to two faces so it can move with the wall. We work on brickwork movement joints, joints between brick and frames and façade panels, and the jobs we see most are weeds or debris growing in open joints and failed seals between different materials.
Outside joints can only be sealed when they’re dry, so work in Pilley is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
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.

Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Fix overflowing gutters above sealed joints
- Make sure movement joints are not pointed over
- Ask before painting over external sealant
- Have failed joints looked at early
Have a quick look at the joints each spring. Watch for splits, edges coming away or growth in the joint.
Leaks behind façade panels and render often go unseen. By the time there’s a damp patch, the damage can be well established so early resealing is worth it.
Signs you need external mastic in Pilley
The wrong product in a moving joint is a classic cause. A stiff, general-purpose sealant can’t cope with a joint that moves a lot, and it tears off the sides.
Common reasons people contact us are:
- Damp patches traced to an open external joint
- Cracked joints where brick meets render or frames
- Joints pointed up with cement by mistake
- Failed sealant between panels on a façade
For site and facilities teams at buildings such as William Gilpin Church of England Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

External mastic in Pilley: local notes
Pilley is within about 2 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on movement joints and outside wall joints, especially on the side facing the sea. Historic houses like Beaulieu Palace House (about 4.4 miles north-east) are a reminder that the area around Pilley 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.
Homes close to Saint Nicholas Chapel include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep. For landlords with property near Lymington Town station, split movement joints are easy to miss on a rental until damp shows inside.
Pilley is about 2 miles north of Lymington, in Hampshire. Pilley gets the same service as everywhere we cover: old sealant removed completely, careful preparation and a 12-month guarantee. Our area takes in 683 places across Hampshire, from the larger towns to small villages. There’s also a page for Southampton, roughly 11 miles from Pilley.

Surface by surface
Render joints
Water behind render can lead to blown patches. A sound joint keeps the render dry behind and protects the render itself.
Copings and trims
Coping joints that leak let water straight down into the wall. Resealing them is a small job that protects a lot.
Questions from Pilley
Is Pilley 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.
Do you work for landlords with property near Lymington Town station?
Yes, we work for landlords and letting agents. You can call 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before work begins.
What is backing rod for?
We fit closed-cell backing rod wherever the joint depth needs controlling. It sets the sealant depth and prevents three-sided bonding.
What do you need from me for a quote?
The location, the problem and the rough size of the job. Photos by email help too.
Do I have to be there?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
How long does external mastic take?
Most jobs take a few hours for a handful of joints, longer for a whole elevation, including the preparation. Your quote will say how long we expect yours to take.
What colours does the sealant come in?
The aim is a neat, even joint in a colour that suits the wall. We’ll talk through colour options before we start, matched as closely as the range allows.
Where is Mr Mastic based?
Our base is in Crawley, and we cover South East England, London and all of Scotland.
DIY versus a professional finish
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
