DIY sealant or a professional job?
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
About our external mastic in Haultwick
A movement joint is a deliberate break that lets a wall expand and contract. The sealant in it has to stretch and squeeze for years, so once it splits or hardens, the joint stops working and water gets in. Common call-outs are for brick movement joints where the sealant has split and joints pointed up with cement by mistake, across joints between brick and frames, façade panels and concrete & block.
In a village or hamlet like Haultwick, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.
You are covered for a year from the day we finish. If anything isn’t right with it, ring 0345 464 0079 or email us.

Work for landlords, hotels and businesses
If you manage several properties in or around Haultwick, several properties can be quoted together. Send us the addresses and the work at each.
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
Why act early in Haultwick
It often makes sense to reseal all the failing joints on an elevation together. They’ve weathered the same way, and access only has to be arranged once. Where a wall is exposed, as many are in small places like Haultwick, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
The cost reflects the work involved, not guesswork. That’s why we ask a few questions first and send you a clear quote before we start.

Haultwick: your questions answered
Is Haultwick within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you help a landlord with a rental near Watton-At-Stone station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before we start.
Can I do it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Is the work guaranteed?
Yes: twelve months. If there’s a problem with our work in that time, tell us and we’ll put it right.
Should I point up the gap in my brickwork?
No, not if it’s a movement joint. Filling it with mortar defeats its purpose, and the wall may crack nearby. We will reseal it with a flexible sealant.
What should I tell you?
The location, the problem and the rough size of the job. If you can, email a few photos.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done.
Do I need to be at home?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you don’t need to watch us work.
What sealant work can’t fix
Some problems need a builder, plumber or other trade rather than us:
- Cracked brickwork or render that needs a builder or plasterer
- Movement that is more than a sealant joint can take
- Adding movement joints to masonry that has none
If in doubt, call 0345 464 0079 or send us an email and we’ll say what we think before booking.
What we seal
- Copings & trims
- Concrete & block
- Render & cladding joints
- Brickwork movement joints

What affects the cost of external mastic
We do not publish a price list, because no two jobs are the same. What we look at:
- How easy the joints are to reach
- Whether there’s mould to deal with
- The old material and how stubborn it is
- Working hours on commercial sites
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
Helping us quote
What to tell us when you ask for a quote:
- Access, such as stairs, a lift or height
- If someone has resealed it before
- The rough size of the job
- Pictures of the joints, sent by email
Need a quote? Please ring 0345 464 0079 or drop us an email and tell us about the job. We’ll explain what we’d do and give you a clear price before work begins.
Walls and rooflines in Haultwick
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Aston Bury (about 3.9 miles west) nearby, there’s older building stock in the area around Haultwick as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
For landlords with property near Watton-At-Stone station, split movement joints are easy to miss on a rental until damp shows inside. If you look after a building such as Munden Church of England Voluntary Controlled Primary School, its movement joints, gutters and trims need looking after like any other building’s. If you live in an older home near Parish Church of All Saints, an extension built onto an older house moves differently, and the joint between them takes the strain.

How it works
All our tools and materials come with us in the van. Once we have agreed what’s being done, the area is protected and the work begins. Most jobs take a few hours to a few days, depending on the length of joint and the access. In a small place like Haultwick, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Before we arrive
- Let us know if you’ve seen damp or leaks
- Mention any parking rules near the property
- Where the joints are inside, avoid wetting them before we arrive

How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Point out the joints to other trades
- Keep soil, plants and ivy away from the joints
- Look over the joints every year, ideally after winter
- Fix overflowing gutters above sealed joints
Look over the joints once a year, ideally after winter. Watch for splits, edges coming away or growth in the joint.
Water getting behind cladding or render can go unnoticed for a long time. When it finally shows inside, the joint may have been open for years.
