External mastic in Eastwood, done properly
External mastic is a job where short cuts show quickly. New sealant over old, joints packed with mortar and beads with no backing rarely last long. We take the old material out and do it properly. We work on joints between brick and frames, copings & trims and render & cladding joints, and common reasons people get in touch are failed sealant between panels on a façade and moss and dirt in joints with no sealant left.
Outbuildings, garages and conservatories around homes in places like Eastwood add more joints to look after. Leaks generally start at a gutter end, a garage door frame or where an extension meets the house.
The work is covered for a year after we finish. If anything is not right with it, call 0345 464 0079 or send us an email.

What the job involves on each surface
Copings and trims
Copings expand and contract through the day, so the joints need a sealant that stays flexible.
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. Their movement joints are sealed over backing rod with a flexible sealant.

What else we do in Eastwood
Outside joints around Eastwood
Eastwood is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Historic houses like Southchurch Hall (about 3.6 miles south-east) are a reminder that the area around Eastwood 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.
Homes close to St David's include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain. For site and facilities teams at buildings such as Heycroft Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

What affects the cost of external mastic
Call for a quick quote. The main things that affect it are:
- Whether old sealant or filler has to be cut out
- Working hours on commercial sites
- The size of the job
- How many rooms, windows or areas are involved
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick 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:
- Access, such as stairs, a lift or height
- Photos by email, if that is easy
- Whether it has been sealed before
- Where the job is, and your postcode
Call for a quick quote, or send an email if you’d rather. Tell us about the joints that need doing and we will explain what’s involved.
DIY versus a professional finish
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Eastwood questions
I let a flat near Southend Airport station. Can you help?
Yes. We work for landlords and letting agents as well as householders, and several properties can be quoted together. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
Do you cover smaller places like Eastwood?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you have insurance?
Yes. We are fully insured, and we’ve been doing sealant work for more than 20 years.
How long will you be here?
A typical job takes a few hours to a few days, depending on the length of joint and the access, including preparation and clearing up. Your quote will say how long we expect yours to take.
Do you use backing rod?
Closed-cell backing rod sets the depth of the sealant and stops it sticking to the back of the joint. Then the sealant bonds to two faces and can move.
What sealant do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We will tell you what we are using and why.
Is there a guarantee?
Yes. Every job comes with a 12-month guarantee.
Where are you based?
We are a Crawley-based firm. We work across South East England, London and Scotland.
How it works
Once we’re on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for a handful of joints, longer for a whole elevation. In a smaller place like Eastwood, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- First, the joints are inspected and the access agreed.
- We cut out the old mastic and rake out anything in the joint.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
How to prepare
- Mention any sign-in or site rules at work premises
- Keep children and pets away from the work area
- Tell us about any previous sealing or DIY attempts

When to call us in Eastwood
Joints sealed without backing rod, or far too deep, rarely last. Sealant bonded to three sides has nowhere to go and tears as soon as the joint widens.
The problems people usually mention when they call include:
- Movement joints with cracked, split or missing sealant
- Gaps where render, brick and frames meet
- Rigid filler in a joint that should flex
- Water getting into walls through failed joints
If you let a flat or house near Southend Airport station, split movement joints are easy to miss on a rental until damp shows inside.
Questions to ask before booking
- Is VAT in the price?
- How hidden problems are handled
- Who turns up on the day
- Which colour the sealant will be
Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Have failed joints looked at early
- Check the sealant is paintable before painting near it
- Point out the joints to other trades
- Keep high-pressure jets off the joints
Don’t let soil, plants or ivy build up against the new joints. Anything that holds water against the joint wears it out sooner.
Small splits are the time to act. At that stage it’s a simple cut out and reseal before water has had years to get in.
