About our external mastic in Totton
Getting the depth right is half the job. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, so it bonds to the two sides only and can stretch. Common call-outs are for brick movement joints where the sealant has split and damp patches traced to an open external joint, across render & cladding joints, brickwork movement joints and copings & trims.
In a town like Totton, older houses with traditional gutters sit alongside newer estates with uPVC rooflines and rendered walls. Gutter joints, fascia trims and the movement joints in newer brickwork all need sealant that can flex.
Your job is guaranteed for a year, as with all our work.

How the visit works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes anything from a few hours to several days, depending on the building. A visit in Totton needs access to the work and a place to park close by. If the job is outside, mention gates, side access and anything above ground floor.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- The old mastic and anything lodged in the joint is removed.
- The joint faces are cleaned and primed where the sealant needs it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Getting ready for the visit
- Try not to wet indoor joints just before the visit
- Let us know if you’ve seen damp or leaks
- Keep children and pets away from the work area

Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Show decorators and builders where the movement joints are
- Wash walls gently around the sealant
- Keep water from gutters off the wall
- Check the sealant is paintable before painting near it
Only paint over the joint if we’ve confirmed the sealant can take paint. Many exterior sealants aren’t designed to be painted and spoil the finish.
A joint that has stopped moving pushes the movement elsewhere, generally as cracking in the brickwork or render nearby. Resealing it early helps prevent that.
When to call us in Totton
Joints sealed without backing rod, or far too deep, rarely last. Sealant bonded to three sides has nowhere to go and rips as the joint opens.
Common reasons people contact us include:
- Weeds or debris growing in open joints
- Gaps where render, brick and frames meet
- Water getting into walls through failed joints
- Old sealant gone brittle and cracked
Homes close to Church of St Winfred include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.

How we quote for external mastic
We quote each job individually. This is what makes a difference:
- How much there is to do
- Access and height
- Any working-time requirements on site
- Any mould that needs treating
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or email us and we will talk you through it.
What we need to know
You don’t need to know the technical terms. Just tell us:
- Roughly how big the job is
- A few photos by email, if you can
- Whether it’s a home or a business
- Where the job is, and your postcode
We don’t publish a price list, because every job is different. Instead, we give you a clear price for your job. To arrange one, ring 0345 464 0079 or send us an email.
When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- Cracks in the bricks or render themselves, away from the joints
- Cutting new joints into brickwork, which is building work rather than sealant work
- Structural movement, which needs a surveyor or engineer
If you are not sure, just ring 0345 464 0079 or email us and we will give you a straight answer.

What do you put in the joint?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Will the new joint stand out?
Exterior sealants are made in a range of colours, from greys and browns to whites and stone shades. We choose the closest to your brick or render so the joint doesn’t draw the eye.
How long does the job take?
A typical job takes 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.
Is it OK to seal over old sealant?
No, because it fails. The old sealant always comes out first, so the new sealant bonds properly.
External mastic in Totton: local notes
Totton 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 Southampton Tudor House and Garden (about 4.5 miles east) nearby, there’s older building stock in the area around Totton as well as newer homes. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
If you look after a building such as Abbotswood Junior School, its movement joints, gutters and trims need looking after like any other building’s. Letting a property close to Totton station? Then outside joints that have cracked can let damp into a rental, so check them between lets.

Surface by surface
Copings and trims
Coping joints that leak let water straight down into the wall. Sealing them early saves the wall below.
Render joints
Rendered walls have joints at beads, openings and changes of material. They’re resealed in a sealant that suits the render.
DIY versus a professional finish
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
