About our external mastic in Roughdown
Joints in render and cladding are easy to overlook until a damp patch appears. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant in a colour to suit. If you are dealing with damp patches traced to an open external joint and rigid filler in a joint that should flex, we can put it right.
In a village or hamlet like Roughdown, older cottages and farm buildings often stand in the open, where walls and rooflines take the weather head on. Joints on those walls need a sealant that moves with the building and stays in place.
Every job comes with our 12-month guarantee, wherever you are in Hampshire.

Surface by surface
Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it. Tell us what the building has when you get in touch.
Copings and trims
Coping and trim joints face rain and sun head on. We reseal them with an exterior sealant suited to the material.
External mastic in Roughdown: local notes
Roughdown is within about 2 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on movement joints and outside wall joints, especially on the side facing the sea. Historic houses like Beaulieu Palace House (about 2.7 miles west) are a reminder that the area around Roughdown 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.
Historic houses such as Beaulieu Palace House, about 2.7 miles west, show how far back building around Roughdown goes. Rented homes near Netley station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets.

DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
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.
When something else is needed
Before you book, it’s worth knowing the limits too:
- Adding movement joints to masonry that has none
- Subsidence or other structural problems
- Cracked brickwork or render that needs a builder or plasterer
If you’re not sure, just call 0345 464 0079 or drop us an email and we’ll give you a straight answer.

When to call us in Roughdown
Sometimes a movement joint was filled with mortar or a rigid filler. The joint can’t move, so the wall cracks somewhere else instead.
The most common problems we see are:
- Joints pointed up with cement by mistake
- Movement joints with cracked, split or missing sealant
- Joints where the bead has come unstuck
- Moss and dirt in joints with no sealant left
Managing a site like Blackfield Primary School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Roughdown: your questions answered
I let a flat near Netley station. Can you help?
Yes, landlords and agents are among the people we work for. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
Does the coastal weather in Roughdown affect outside sealant?
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.
Do you do commercial work?
Yes. Hotels, offices and other businesses use us, and we are fully insured.
What is a movement joint?
Walls move with heat, cold and moisture, so long walls have planned gaps to take that movement. It’s closed with backing rod and a flexible sealant.
Are you insured?
Yes, we’re fully insured for every job we do.
Will you leave a mess?
Tidy work is part of the job. We protect what’s around the joints, and the area is left clean when we finish.
How often do external joints need resealing?
It varies with how exposed the wall is and how much the joint moves. Look for splits, hardening or edges coming away.
Can you seal joints between render and window frames?
Yes. Different materials move at different rates, so the joint between them must be flexible. The sealant is matched to both sides.

How the visit works
There’s no need to move everything out, only the area right around the joints. Everything nearby is protected, and the work takes a few hours for a handful of joints, longer for a whole elevation for a typical job. In a small place like Roughdown, 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 checking each joint, agreeing the ones to redo and how we’ll reach them.
- The old mastic and anything lodged in the joint is removed.
- We clean both faces of the joint and prime them where the product calls for it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can
- Mention any parking rules near the property
- Mention any sign-in or site rules at work premises
