External & façade joints in Lowford, Hampshire
Problem with your movement joints in Lowford? We cut out the old, prepare the joints and apply the right sealant, and the work is guaranteed for a year.
- Brick movement joints where the sealant has split
- Cracked joints where brick meets render or frames
- Sealant that has lost its bond to the brick or render
External mastic in Lowford
Movement joints let brickwork, render and cladding expand and shrink without cracking. The sealant in it has to stretch and squeeze for years, so once it splits or hardens, the joint stops working and water gets in. We work on joints between brick and frames, render & cladding joints and brickwork movement joints, and the jobs we see most are sealant that has lost its bond to the brick or render and leaking joints around cladding and façade panels.
Outbuildings, garages and conservatories around homes in places like Lowford add more joints to look after. Leaks usually start at a gutter end, a garage door frame or where an extension meets the house.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we’ll put it right.

The process
We bring everything the job needs with us. Once we’ve agreed what’s being done, the area is protected and the work begins. Most jobs take a few hours for a handful of joints, longer for a whole elevation. A visit to Lowford is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We start by walking round the building and agreeing the joints and the access.
- We cut out the old mastic and rake out anything in the joint.
- Joint faces are cleaned back and primed if the sealant needs it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
Before we arrive
- Tell us about any previous sealing or DIY attempts
- Plan for the work area to be out of bounds to pets and children
- For indoor joints, keep the area dry beforehand if you can

Walls and rooflines in Lowford
Lowford 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. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. With historic houses such as Medieval Merchant's House (about 3.7 miles west) nearby, there’s older building stock in the area around Lowford as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
If you look after a building such as Bursledon Church of England Infant School, its movement joints, gutters and trims need looking after like any other building’s. Homes close to St Paul’s Church include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain.

Different surfaces, different methods
Render joints
Render has movement joints and stop beads that need sealing. We reseal them with a flexible exterior sealant that suits the render colour.
Cladding and façade panels
Cladding and façade panels are generally separated by sealed joints. We reseal them with a sealant suited to the panel material.
Leave it or put it right?
Running new sealant over the old bead rarely lasts. New sealant doesn’t bond well to old, weathered sealant, so the old joint is cut out fully first. In a smaller place like Lowford, 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.

What we are called out for in Lowford
Every building moves. Brickwork grows a little over the years, blockwork and concrete shrink, and all of it moves with heat and moisture. The sealant in the movement joints takes that strain.
It’s worth asking for a quote if you see:
- Weeds or debris growing in open joints
- Rain getting behind render or cladding at a joint
- Rigid filler in a joint that should flex
- Brick movement joints where the sealant has split
Rented homes near Bursledon station change hands often, and split movement joints are easy to miss on a rental until damp shows inside.

How to look after the new joints
Aftercare is simple:
- Make sure movement joints aren’t pointed over
- Avoid pressure-washing directly into sealant joints
- Point out the joints to other trades
- Ask before painting over external sealant
Have a quick look at the joints each spring. Splits, gaps at the edges or plants in the joint are early warning signs.
If you can see gaps, plants or bare sections in a joint, have it checked. Early work is quicker and leaves a better finish.
What affects the quote in Lowford
Every job gets its own quote. This is what makes a difference:
- Mould in or behind the old joints

Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we will explain what it covers.

You do not need to know the technical terms. Just tell us:
- The address or postcode of the job

- Access, such as stairs, a lift or height
- The type of property

Common questions in Lowford
Does the coastal weather in Lowford affect outside sealant?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. Walls facing the sea are generally the first to need attention.
Do you cover smaller places like Lowford?
Yes. Lowford is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do I need to be at home?
We need access to the joints, so we’ll agree that with you when we book. Indoors, that generally means someone at home.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do. We can talk about working times when we quote.
Are you fully insured?
Yes. We are fully insured, and we can confirm the details when we quote.
Can you reach joints on upper floors?
Each building is different. Send us photos and a rough idea of the height.
What is backing rod for?
The foam is closed-cell backing rod. It keeps the sealant at the right depth and bonded to the sides only, which would stop it stretching.
Should I point up the gap in my brickwork?
No. Mortar locks the joint solid, so the movement cracks the wall elsewhere. It needs a flexible sealant over backing rod.
