External Mastic in Chandler's Ford
We cover Chandler's Ford for sealing brickwork movement joints, render, cladding and façade joints. Old sealant removed completely, joints prepared properly and a one-year guarantee.
- Gaps where render, brick and frames meet
- Joints where the bead has come unstuck
- Failed sealant between panels on a façade
What we are called out for in Chandler's Ford
Using the wrong sealant is another common reason. A stiff, general-purpose sealant can’t cope with a joint that moves a lot, so it pulls away from the edges.
If you can see any of these, it’s time to have the joints looked at:
- Damp patches traced to an open external joint
- Gaps where render, brick and frames meet
- Rigid filler in a joint that should flex
- Moss and dirt in joints with no sealant left
For an older house near a landmark such as St Boniface, older walls, gutters and the joints where extensions meet them need a flexible sealant.
Before you book anyone
- Whether they seal over old material or remove it
- Whether they’re fully insured
- When the joint can take water or movement
- What preparation is included
External mastic in Chandler's Ford
External mastic is a job where short cuts show quickly. Overfilled joints, missing backing rod and sealant laid over old sealant rarely last long. We strip the joint back and start again. If you have cracked joints where brick meets render or frames and failed sealant between panels on a façade, we can help.
In a town like Chandler's Ford, 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.
A 12-month guarantee comes as standard, so you are not left on your own once the job is done.

What affects the quote in Chandler's Ford
Every job gets its own quote. This is what makes a difference:
- The old material and how stubborn it is
- The size of the job
- Which sealant suits the joint
- When we can work, for business premises
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first and agree the price before starting.
Asking for a quote
You don’t need to know the technical terms. It helps if you can tell us:
- Whether it’s a home or a business
- What’s wrong with the joints now
- A few photos by email, if you can
- Access, such as stairs, a lift or height
There’s no standard price list. Instead, your job gets its own clear quote. To get started, phone 0345 464 0079 or email us.
What happens if it’s left?
Low-modulus sealants stretch easily, so they put less strain on the joint edges. That protects surfaces like brick, render and concrete. Too stiff a sealant can pull at the edges and break them. Draughts from a gap round a frame, damp under a sill or water behind a bath panel all start small, and early is when they’re cheapest and quickest to sort.
Doing several joints on one visit normally makes better use of the time than several visits. We’ll give you a clear quote for the lot.

Your questions about external mastic in Chandler's Ford
Do you work for landlords with property near Chandlers Ford station?

Can you do external mastic in Chandler's Ford?
Yes, Chandler's Ford is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or send us an email and tell us what needs doing.
Do I need to be at home?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Can you do several jobs on one visit?
Yes, we can. Several rooms, windows or areas can go on one quote.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint before resealing.
What’s an expansion joint in brickwork?
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 ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Should I point up the gap in my brickwork?
No. Mortar locks the joint solid, so the wall cracks somewhere else instead. It needs a flexible sealant over backing rod.

What else we do in Chandler's Ford
What the job involves on each surface
Joints between dissimilar materials
Brick against render, concrete against metal, stone against timber: every change of material is a joint. We seal the joint with a flexible exterior sealant.
Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it or an approved alternative. Tell us what the building has when you get in touch.
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Tell anyone working on the walls about the movement joints
- Act on the first splits you see
- Check external joints each spring
- Keep soil, plants and ivy away from the joints
Only paint over the joint if we’ve confirmed the sealant can take paint. Many exterior sealants aren’t designed to be painted, and paint can crack as the joint moves.
A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Resealing it early helps prevent that.
For landlords and businesses
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we’ll quote.
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
How it works
At the end, we look at the finished work together and explain the cure time. The visit itself usually takes a few hours to a few days, depending on the length of joint and the access, depending on the amount of work. Parking in a town like Chandler's Ford is usually straightforward, but tell us if there’s a driveway or any restrictions, and let us know if the work is upstairs, in a flat or up high outside.
- 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.
- We apply the sealant, tool it and check the whole run.
How to prepare
- For indoor joints, keep the area dry beforehand if you can
- Keep children and pets away from the work area
- Mention any sign-in or site rules at work premises

Advice
Chandler's Ford buildings and the weather
Historic houses like South Stoneham House (about 3.4 miles south) are a reminder that the area around Chandler's Ford has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you look after a building such as Chandler's Ford Infant School, larger buildings have long runs of movement joint that eventually need resealing. Rented homes near Chandlers Ford station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets.
