The process
Before we leave, we go over the finished joints with you and tell you how long to leave it. The work normally takes a few hours to a few days, depending on the length of joint and the access, depending on the size of the job. Somewhere as small as Yarmouth, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
- The old mastic and anything lodged in the joint is removed.
- 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.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know about parking restrictions

Advice
How we handle external mastic in Yarmouth
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 take the old material out and do it properly. We work on brickwork movement joints, render & cladding joints and concrete & block, and the jobs we see most are gaps where render, brick and frames meet and leaking joints around cladding and façade panels.
Around Yarmouth, older buildings can be stone, brick or timber-framed, many with extensions added later. Where one material meets another is where water normally gets in.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

External mastic in Yarmouth: local notes
Yarmouth is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on movement joints and outside wall joints, especially on the side facing the sea. Historic houses like Mottistone Manor (about 4.8 miles south-east) are a reminder that the area around Yarmouth 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.
If you let a flat or house near Lymington Pier station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. Schools such as Yarmouth Church of England Aided Primary School are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. For an older house near a landmark such as St. James' Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.
Yarmouth is about 4 miles south-east of Lymington, in the Isle of Wight.

Yarmouth is one of 125 places in the Isle of Wight we cover for external mastic. There’s also a page for Southampton, roughly 15 miles from Yarmouth.

How the job changes by surface
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.
Brickwork movement joints
People sometimes point up a brick movement joint by mistake. If that is happened, we rake it out and reseal it properly where it can be done safely.
Why it’s worth doing now in Yarmouth
Mortar or ordinary filler might look like a quick way to close an open joint, but it stops the joint moving. The wall then cracks somewhere else. A flexible sealant over backing rod is what the joint needs. Around Yarmouth, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.

DIY versus a professional finish
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
What affects the cost of external mastic
You’ll get a clear quote before any work starts. It takes into account:
- Mould in or behind the old joints
- Working hours on commercial sites
- How much old sealant there is and how hard it is to remove
- The amount of work
Doing several joints on one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.
What to tell us for a quote
To make quoting easier, let us know:
- Access, such as stairs, a lift or height
- Any previous sealing or DIY work
- Whether it’s a home or a business
- Where the job is, and your postcode

Landlords, agents and businesses in Yarmouth
In hotels, rooms out of use cost money, so we plan the work room by room. We’ve worked in hotels as well as homes and businesses.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
Looking after it afterwards
Good habits help new joints last longer. Our tips:
- Avoid pressure-washing directly into sealant joints
- Show decorators and builders where the movement joints are
- Have failed joints looked at early
- Keep movement joints as flexible joints, not mortar
Follow the cure time we give you before the joint is knocked or disturbed. The surface skins over quickly, but full cure takes longer.
An open movement joint lets rain into the wall every time it pours. That can lead to damp patches, staining and frost damage, all bigger jobs than a reseal.
FAQs for Yarmouth
Is external mastic in a coastal place like Yarmouth any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. Walls facing the sea are normally the first to need attention.
Do you work for landlords with property near Lymington Pier station?
Yes. We work for landlords and agents as well as homeowners, and several properties can go on one quote. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear price.
Do you work for hotels and businesses?
Yes. We’ve worked for hotels, offices and other businesses, and we are fully insured.
Should I try DIY first?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
How long before the joint can be used?
Many sealants skin over quickly but take longer to cure fully. We’ll give you the cure time for the product we used.
Do you guarantee your work?
Yes: twelve months. If anything isn’t right with the work within the year, let us know and we’ll sort it.
Can you seal joints between two different materials?
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.
Will it make a mess?
Tidy work is part of the job. We protect what’s around the joints, and the area is left clean when we finish.
