Wivenhoe Cross External Mastic

External mastic for homes and businesses in Wivenhoe Cross
Getting the depth right is half the job. Backing rod controls how deep the sealant goes and keeps it off the back of the joint, leaving it bonded to two faces so it can move with the wall. We work on concrete & block, joints between brick and frames and copings & trims, and the jobs we see most are moss and dirt in joints with no sealant left and joints with sealant missing in places.
In and around Wivenhoe Cross, older properties sit alongside newer ones, each with its own outside joints. Older gutters and trims need their joints resealed; newer brick and render need their movement joints kept sound.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

Outside joints around Wivenhoe Cross
Wivenhoe Cross is within about 2 miles of 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. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you live in an older home near The Church of St Mary, an extension built onto an older house moves differently, and the joint between them takes the strain. Letting a property close to Wivenhoe station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Why act early in Wivenhoe Cross
A properly done movement joint is an even line in a colour that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner. In an older home around Wivenhoe Cross, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we will explain what it covers.

Looking after it afterwards
After the cure time, these simple habits help:
- Walk round the building once a year and look at the joints
- Leave the joints unpainted unless we’ve said otherwise
- Deal with leaking gutters that soak the joints below
- Act on the first splits you see
Don’t let soil, plants or ivy build up against the new joints. Anything that holds water against the joint wears it out sooner.
Leave a failed movement joint and water keeps getting into the wall. That can lead to damp patches, staining and frost damage which cost more to put right than the joint.
How the visit works
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, do the work and tidy away. Most jobs take a few hours for a handful of joints, longer for a whole elevation. In a smaller place like Wivenhoe Cross, 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.
- We start by walking round the building and agreeing the joints and the access.
- We cut out the old mastic and rake out anything in the joint.
- Joint faces are cleaned back and primed if the sealant needs it.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- Try not to wet indoor joints just before the visit
- For business premises, tell us about site rules or sign-in

How we quote for external mastic
The quote reflects the job in front of us. We take into account:
- Whether old sealant or filler has to be cut out
- Mould in or behind the old joints
- The number of rooms or windows
- The type of sealant required
Doing several joints on one visit generally makes better use of the time than several visits, so tell us about everything that needs sealing. We will give you a clear price for the lot.
What to tell us for a quote
What to tell us when you ask for a quote:
- Any access issues, like height or stairs
- The type of property
- What’s wrong with the joints now
- The address or postcode of the job
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and email photos if that is easy.
Do you need external mastic in Wivenhoe Cross?
Some movement joints have been pointed up with mortar by mistake. The joint can’t move, so the wall cracks somewhere else instead.
Keep an eye out for any of the following:
- Weathered mastic that no longer stretches
- Failed seals between different materials
- Moss and dirt in joints with no sealant left
- Joints with sealant missing in places
If you look after a building such as Broomgrove Infant School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

For landlords and businesses
We also work for property managers and facilities teams in Wivenhoe Cross and across Essex. Several sites can go on one quote, and we’re fully insured.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
When something else is needed
Sealant isn’t the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Render that’s blown, hollow or coming away
- Cracking across the wall rather than at a joint
- Damp that is not coming from the joint
If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think.
Surfaces we seal

Wivenhoe Cross questions
Does living near the coast affect external mastic in Wivenhoe Cross?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Do you work for landlords with property near Wivenhoe station?
Yes, we work for landlords and agents. You can call 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before we start.
When will the joints need doing again?
That depends on the wall, the weather and the movement. Look for splits, hardening or edges coming away, and reseal at that point.
Can I add another job to the visit?
Yes. Several rooms, windows or areas can go on one quote.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. Working times can be discussed when we quote.
What does external mastic cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we will talk you through it.
What do you need from me for a quote?
A short description and the location. If we need more, we’ll ask.
Does someone need to be in?
We need access to the joints, so we will agree that with you when we book. Indoors, that usually means someone at home.
