Chigwell External Mastic
Sealing brickwork movement joints, render, cladding and façade joints in Chigwell, with a one-year guarantee on every job. Call for a quick quote.
- Cracked joints where brick meets render or frames
- Weeds or debris growing in open joints
- Joints where the bead has come unstuck
Should I try it myself first?
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
External mastic in Chigwell, done properly
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. We pick a colour that sits well with the wall. We work on copings & trims, brickwork movement joints and joints between brick and frames, and people most often call us about sealant that has lost its bond to the brick or render and failed sealant between panels on a façade.
In a smaller place like Chigwell, some homes face open ground, so exposed walls and rooflines take more wind-driven rain. Joints on those sides are usually the first to go.
You get a one-year guarantee, the same in Chigwell as everywhere else we work.

How we quote for external mastic
We do not publish a price list, because no two jobs are the same. The quote depends on:
- Mould in or behind the old joints
- Whether the work is at height
- When we can work, for business premises
- How many areas need sealing
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Call for a quick quote and we’ll explain what it covers.
Asking for a quote
When you contact us, these details help:
- What the problem is, such as mould, gaps, leaks or cracking
- Where the property is
- Whether it’s a home or a business
- How we’d reach the joints
For a quote, ring 0345 464 0079 or send us an email with the location and a short description of the problem. You will have a clear quote before any work starts.
How it works
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours to a few days, depending on the length of joint and the access. In a smaller place like Chigwell, parking is seldom the issue; lanes, gates and long drives are worth mentioning. 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.
- The old mastic and anything lodged in the joint is removed.
- 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.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Getting ready for the visit
- Move anything stored near the joints
- Keep pets and children clear of the area while we work
- Mention any leaks or damp you’ve noticed
Getting a quote
Getting a quote is simple: let us know the job and the location. A few photos by email make the job easier to understand, and we will come back to you with a quote.

External mastic in Chigwell: local notes
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. Historic houses like Valentines Mansion (about 2.9 miles south) are a reminder that the area around Chigwell has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
For landlords with property near Chingford station, split movement joints are easy to miss on a rental until damp shows inside. Homes close to St Winifred include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.

Questions from Chigwell
Will you come out to Chigwell?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can you help a landlord with a rental near Chingford station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can phone 0345 464 0079 or email us with the details for a clear quote.
Do the sealants smell?
It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we’re fully insured.
Can you work on commercial sites?
Yes, regularly. Larger jobs can be planned room by room or area by area to suit the site.
How long should I leave it?
Different products cure at different speeds, so follow the cure time we give you when we finish.
Do you have insurance?
Yes, we’re fully insured for every job we do.
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 reseal at that point.
When to call us in Chigwell
Some movement joints have been pointed up with mortar. With the joint locked solid, the movement turns into cracks elsewhere in the wall.
Signs it’s time to call us include:
- Plants rooting in failed movement joints
- Joints with sealant missing in places
- Failed sealant between panels on a façade
- Sealant that has lost its bond to the brick or render
Schools such as Limes Farm Infant School and Nursery are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.

How the job changes by surface
Cladding and façade panels
Panels heat up and cool down quickly, so the joint sealant has to cope with frequent movement. We choose the product to suit.
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. We reseal their joints with backing rod and a flexible product.
When it isn’t the sealant
To be straight with you, some problems need a different trade:
- Loose or hollow render, which needs re-rendering
- Structural movement, which needs a surveyor or engineer
- Damp that is not coming from the joint
Not sure which it is? You can call 0345 464 0079 or drop us an email and we’ll tell you honestly.
