How we handle external mastic in Bursledon
Low-level joints can usually be done from the ground. For joints higher up, give us some details of the building and we’ll confirm what access is needed. Typical jobs include weeds or debris growing in open joints and damp patches traced to an open external joint, on joints between brick and frames, concrete & block and brickwork movement joints.
Around Bursledon, garages, outbuildings and extensions all add to the joints on the outside of a home. Gutter ends, garage door frames and the joints where an extension meets the house are typical spots for leaks.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or drop us an email.

Work for landlords, hotels and businesses

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
Bursledon: your questions answered
I let a flat near Bursledon station. Can you help?
Yes. We work for landlords and letting agents as well as householders. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we will give you a clear quote.
Does the coastal weather in Bursledon affect outside sealant?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
Can you quote for more than one area?
Of course. Combining jobs makes good use of the visit.
Is it messy?
We keep the work tidy. Nearby surfaces are protected, and we clear up when we are done.
Do you use backing rod?
Backing rod goes into deeper joints as a matter of course. It controls the depth and stops the sealant bonding to the back, so the joint can move.
Do you cover Bursledon?
Yes. We cover Bursledon and the rest of Hampshire. To book, phone 0345 464 0079 or email us.
Can you seal over the old sealant?
No. We remove every bit of old sealant first.
What do you need from me for a quote?
Just the basics: the address or postcode, what’s wrong and any access issues. Then call 0345 464 0079 or drop us an email.
What affects the quote in Bursledon
You will get a clear quote before we start. It’s based on:
- The product the joint needs
- The old material and how stubborn it is
- How easy the joints are to reach
- Any mould that needs treating
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.
Helping us quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Where the property is
- If it’s domestic, commercial or a hotel
- Roughly how big the job is
- Pictures of the joints, sent by email
Call for a quick quote, or send an email if you’d rather. Tell us about the joints that need doing and we will talk you through the work.

What else we do in Bursledon
Walls and rooflines in Bursledon
Bursledon 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. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For landlords with property near Bursledon station, split movement joints are easy to miss on a rental until damp shows inside. If you live in an older home near St Paul’s Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep.
Bursledon is about 2 miles south of Hedge End, in Hampshire. Our applicators cover external mastic for homes and businesses in Bursledon and the surrounding area, as part of our work across Hampshire. Bursledon is one of 683 places in Hampshire we cover for external mastic.

What’s near Bursledon

Why act early in Bursledon
The longer a joint stays open, the more water the wall takes in. In cold weather, frost can damage wet brick and render around the joint, so the problem grows beyond the joint itself. In an older home around Bursledon, damp from a failed joint can get into timber and plaster, and that’s a much bigger job than renewing the sealant.

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 to a few days, depending on the length of joint and the access for a typical job. In a smaller place like Bursledon, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- Each joint is checked and the colour of the new sealant agreed.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Preparing for the visit
- Let us know about earlier repairs to the joints
- Let us know if you’ve seen damp or leaks
- Mention any parking rules near the property
Getting a quote
Asking for a quote is easy: tell us what needs doing and where and its rough size. A few photos by email make the job easier to understand.
Related advice
What we are called out for in Bursledon
Sometimes a movement joint was filled with mortar or a rigid filler, often by someone who didn’t know what it was for. The joint can’t move, so the wall cracks somewhere else instead.
Look out for any of the following:
- Leaking joints around cladding and façade panels
- Sealant pulling away from one side of the joint
- Joints pointed up with cement by mistake
- Weathered mastic that no longer stretches
Schools such as Bursledon Church of England Infant School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Aftercare tips
To keep the joints looking good and working properly:
- Ask before painting over external sealant
- Never let anyone fill a movement joint with mortar
- Act on the first splits you see
- Look over the joints every year, ideally after winter
Keep the joints clear of soil, plants and climbing growth. Damp material against the sealant shortens its life.
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.
What we cannot put right
It helps to know what we cannot do:
- Rising or penetrating damp from elsewhere in the wall
- Walls that need new movement joints cut into them
- Cracks in the bricks or render themselves, away from the joints
If in doubt, phone 0345 464 0079 or email us and we will say what we think.
Surfaces we seal
