How it works
We bring everything the job needs with us. Once we’ve agreed what’s being done, we protect the area and start. Most jobs take anything from a few hours to several days, depending on the building. Parking around Hawkwell is normally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- First we look over the joints with you, agree which to renew and talk through access.
- Old sealant and any debris are cut and raked out.
- Both sides are cleaned back to sound material and primed if needed.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Preparing for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Mention any leaks or damp you’ve noticed
- Tell us about any previous sealing or DIY attempts

Related advice
External mastic for homes and businesses in Hawkwell
Short cuts in external joints show up within a season or two. New sealant over old, joints packed with mortar and beads with no backing all tend to fail early. We strip the joint back and start again. If you have failed seals between different materials and hard, crazed mastic that has stopped moving, we can put it right, whatever the surface.
Houses in smaller places like Hawkwell can stand more in the open than those in a built-up town, so exposed walls and rooflines take more wind-driven rain. Joints on those sides are generally the first to go.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

External mastic in Hawkwell: local notes
Historic houses like Southchurch Hall (about 4.9 miles south-east) are a reminder that the area around Hawkwell 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. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Managing a site like Westerings Primary Academy? Then its movement joints, gutters and trims need looking after like any other building’s. If you let a flat or house near Hockley station, outside joints that have cracked can let damp into a rental, so check them between lets.

Common problems we fix in Hawkwell
Joints sealed without backing rod, or far too deep, rarely last. If the sealant sticks to the back as well as the sides, it cannot stretch and tears as soon as the joint widens.
If you can see any of these, it’s time to have the joints looked at:
- Leaking joints around cladding and façade panels
- Old sealant gone brittle and cracked
- Cracked joints where brick meets render or frames
- Water getting into walls through failed joints
For an older house near a landmark such as Emmanuel Parish Church, an extension built onto an older house moves differently, and the joint between them takes the strain.
What your quote should include
- What happens if the job turns out different
- The length of the guarantee
- Whether the sealant suits the joint
- What insurance they hold
What happens if it’s left?
The longer a joint stays open, the more water the wall takes in. Wet masonry is more easily damaged by frost near the open joint, so the damage spreads beyond the joint. In an older home around Hawkwell, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first and agree the price before starting.

Your questions about external mastic in Hawkwell
Is Hawkwell within the area you cover?
Yes. Hawkwell is within the area we cover, which takes in towns, villages and rural addresses. 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 Hockley station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
What is a movement joint?
Walls move with heat, cold and moisture, so long walls have planned gaps to take that movement. It’s closed with backing rod and a flexible sealant.
What is backing rod for?
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.
How long does external mastic last?
That depends on the wall, the weather and the movement. Signs to watch for are cracking, hardening and gaps at the edges and have them redone then.
Can you do several jobs on one visit?
Of course. Doing several areas at once is generally more efficient.
Are you fully insured?
Yes. We are fully insured, and we can confirm the details when we quote.
Do you do commercial work?
Yes. We’ve worked for hotels, offices and other 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.
Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
Looking after it afterwards
Joint life depends on how it’s used and looked after. We suggest:
- Make sure movement joints aren’t pointed over
- Keep water from gutters off the wall
- Check external joints each spring
- Act on the first splits you see
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They must stay as flexible joints, never rendered or pointed over.
Leaks behind façade panels and render often go unseen. When it finally shows inside, the joint may have been open for years so early resealing is worth it.
