FAQs for Toothill
Can you do external mastic in Toothill?
Yes, Toothill is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or send us an email and let us know what needs doing.
I let a flat near Romsey station. Can you help?
Yes, we work for landlords and agents. You can call 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before any work starts.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We will tell you what we are using and why.
What information do you need?
Just the basics: the address or postcode, what’s wrong and any access issues. Then call 0345 464 0079 or email us.
Can you seal joints between render and window frames?
Yes. Materials like render, brick, metal and uPVC all move differently, so a flexible sealant is needed where they meet. The sealant is matched to both sides.
What does external mastic cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we’ll talk you through it.
Should I point up the gap in my brickwork?
No. Rigid materials can’t move with the wall. If it has already been filled, we can generally cut it out and reseal it.
Do the sealants smell?
Possibly a little. It fades as the sealant cures.
External mastic for homes and businesses in Toothill
External mastic is a job where short cuts show quickly. Overfilled joints, missing backing rod and sealant laid over old sealant all tend to fail early. We strip the joint back and start again. We’re often asked to deal with joints pointed up with cement by mistake and leaking joints around cladding and façade panels, on façade panels, joints between brick and frames and copings & trims.
Around Toothill, older buildings can be stone, brick or timber-framed, many with extensions added later. The joints where those materials meet are the weak points.
There’s a 12-month guarantee on every job.

Walls and rooflines in Toothill
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like South Stoneham House (about 4.3 miles south-east) are a reminder that the area around Toothill has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material.
For site and facilities teams at buildings such as The Mountbatten School, larger buildings have long runs of movement joint that eventually need resealing. If you live in an older home near Church of St John, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

How it works

For a village or hamlet like Toothill, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First we look over the joints with you, agree which to renew and talk through access.
- We cut out the failed sealant and rake out any dirt or growth.
- Both sides are cleaned back to sound material and primed if needed.
- 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.

For landlords and businesses
If you manage several properties in or around Toothill, several properties can be quoted together. Just tell us the addresses and what each one needs.
Letting agents often deal with us directly. Tell us the address, the job and how access works and we’ll give you a quote.
Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Look over the joints every year, ideally after winter
- Keep movement joints as flexible joints, not mortar
- Don’t let climbing plants root in the sealant
- Ask before painting over external sealant
Make sure anyone working on the wall later knows where the movement joints are. They must stay as flexible joints, never rendered or pointed over.
Once a joint cannot move, the wall finds another way, often as cracks near the joint. Catch it early and you reduce the risk.
Quotes for external mastic in Toothill
Every job gets its own quote. This is what makes a difference:
- Access and height
- The number and length of the joints
- Whether old sealant or filler has to be cut out
- The product the joint needs
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we’ll explain what it covers.
Asking for a quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- The address or postcode of the job
- If someone has resealed it before
- Any access issues, like height or stairs
- What’s wrong with the joints now
It all starts with a short chat. Describe the problem, the location and the size of the job, and we will explain how we’d tackle it. Whenever you are ready, ring 0345 464 0079 or drop us an email.
DIY sealant or a professional job?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
What we can’t put right
Sealant is not the answer to every problem, and we’d rather say so up front. Sealant won’t put right:
- Cracking across the wall rather than at a joint
- Rising or penetrating damp from elsewhere in the wall
- Subsidence or other structural problems
Not sure which it is? You can call 0345 464 0079 or drop us an email and we will tell you honestly before you book.
What we seal
- Brickwork movement joints
- Copings & trims
- Concrete & block
- Joints between brick and frames
- Façade panels
- Render & cladding joints
What we’re called out for in Toothill
Sunlight, wet weather and frost wear exterior sealant down. Over the years it hardens, cracks on the surface and loses its give, so the joint eventually tears or comes away from one side.
The most common problems we see are:
- Damp patches traced to an open external joint
- Movement joints filled with mortar instead of sealant
- Movement joints with cracked, split or missing sealant
- Cracked joints where brick meets render or frames
For landlords with property near Romsey station, outside joints that have cracked can let damp into a rental, so check them between lets.
