How we quote for external mastic
Your quote is based on your job. We take into account:
- The number and length of the joints
- Whether the work is at height
- When we can work, for business premises
- Mould in or behind the old joints
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
Asking for a quote
There’s no need for technical detail. Just tell us:
- The rough size of the job
- Access, such as stairs, a lift or height
- What the problem is, such as mould, gaps, leaks or cracking
- Photos by email, if that’s easy

About our external mastic in Lymore
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product. Common call-outs are for joints where the bead has come unstuck and weathered mastic that no longer stretches, across brickwork movement joints, façade panels and copings & trims.
Older homes in small places like Lymore may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points.
We stand behind the work with a 12-month guarantee, so you are covered after we have gone.

Surface by surface
Cladding and façade panels
Panel systems often rely on sealant between and around the panels. We reseal them with a sealant suited to the panel material.
Copings and trims
Joints in copings, parapets and trims are exposed to the worst of the weather. Each is resealed with a weatherproof, flexible sealant.
Lymore buildings and the weather
Lymore is close to 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. 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.
Managing a site like Milford-on-Sea Church of England Primary School? Then larger buildings have long runs of movement joint that eventually need resealing. For landlords with property near Lymington Town station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. Homes close to Church of All Saints include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain.

Can I do it myself?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
The process
The work is kept neat and contained to the joints we’re treating, so you can carry on as normal. The job generally takes anything from a few hours to several days, depending on the building, and we explain the cure time before we leave. Somewhere like Lymore needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- 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.
- We gun in low-modulus sealant and tool it neatly.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can
- Mention any parking rules near the property
- Clear the area around the work

How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Keep water from gutters off the wall
- Have failed joints looked at early
- Never let anyone fill a movement joint with mortar
- Check the sealant is paintable before painting near it
Make sure anyone working on the wall later knows where the movement joints are. They should be kept open and resealed, not filled.
Gaps, plants or missing sealant in a joint are worth getting looked at. Earlier resealing means a smaller job and a better result.
Landlords, agents and businesses in Lymore
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
What we cannot put right
We’d rather tell you now than do work that will not last, so these are the limits:
- Loose or hollow render, which needs re-rendering
- Cracked brickwork or render that needs a builder or plasterer
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
If in doubt, call 0345 464 0079 or send us an email and we’ll say what we think.
What we seal

Common questions in Lymore
Does the coastal weather in Lymore affect outside sealant?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
I let a flat near Lymington Town station. Can you help?
Yes. We work for letting agents and landlords as well as householders. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we’ll send you a clear quote.
Can a movement joint be filled with mortar?
No, not if it’s a movement joint. Pointing it stops it working. We’ll reseal it with a flexible sealant.
Can you seal joints between render and window frames?
Yes. Joints between dissimilar materials are a big part of external work. The sealant is chosen to bond to both sides with primer where required.
Are you insured?
Yes. We are fully insured, and we can confirm the details when we quote.
Does someone need to be in?
If the work is inside, we need someone to let us in. Once we have agreed the job, you do not need to watch us work.
Will there be a smell?
It depends on the product. Some smell for a while, some hardly at all.
Should I try DIY first?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
