Ningwood External Mastic
Sealing brickwork movement joints, render, cladding and façade joints for homeowners, landlords and businesses in Ningwood. Fully insured, ARBOMaster approved and guaranteed for a year.
- Sealant that has lost its bond to the brick or render
- Hard, crazed mastic that has stopped moving
- Damp patches traced to an open external joint
DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
How we handle external mastic in Ningwood
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product in a colour to suit. If you have brick movement joints where the sealant has split and weeds or debris growing in open joints, we can put it right.
Somewhere as small as Ningwood, homes and farm buildings often face open ground, where walls and rooflines take the weather head on. Joints on those walls need a sealant that moves with the building and stays in place.
You are covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or email us.

For landlords and businesses
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.
Failed sealant is one of the commonest items on a check-out report. We can quote for more than one property at once.
Other services in Ningwood
Outside joints around Ningwood
Ningwood is within about 2 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on movement joints and outside wall joints, especially on the side facing the sea. With historic houses such as Swainston Manor (about 2.5 miles east) nearby, there’s older building stock in the area around Ningwood as well as newer homes. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
For an older house near a landmark such as Church of St. Michael the Archangel, an extension built onto an older house moves differently, and the joint between them takes the strain. If you look after a building such as Shalfleet Church of England Primary School, larger buildings have long runs of movement joint that eventually need resealing.

Local landmarks in Ningwood

What the job involves on each surface
Joints between dissimilar materials
Where a frame or panel meets masonry, water often finds a way in. The old joint is removed and a sealant that bonds to both sides goes in.
Copings and trims
A failed coping joint lets water into the top of the wall. Sealing them early saves the wall below.
What affects the cost of external mastic
There’s no set price list. What we look at:
- Access and height
- How many rooms, windows or areas are involved
- The size of the job
- The old material and how stubborn it is
Doing several joints on one visit generally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear price for the lot.
What to tell us for a quote
Photos help, but a description is a good start. Please mention:
- What’s wrong with the joints now
- Where the job is, and your postcode
- Whether it’s a home or a business
- Photos by email, if that is easy
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we’ll explain how we’d tackle it. Whenever you’re ready, call 0345 464 0079 or drop us an email.
What we can’t put right
In fairness, some problems need a different trade:
- Damp that is not coming from the joint
- Cracks in the bricks or render themselves, away from the joints
- Adding movement joints to masonry that has none
Not sure which it is? You can ring 0345 464 0079 or email us and we will tell you honestly.
Where we work in Ningwood
- Concrete & block
- Brickwork movement joints
- Façade panels
- Copings & trims
- Joints between brick and frames
- Render & cladding joints
Keeping the joints in good condition
So the new joints stay in good condition:
- Leave the joints unpainted unless we have said otherwise
- Make sure movement joints aren’t pointed over
- Have failed joints looked at early
- Keep soil, plants and ivy away from the joints
Have a quick look at the joints each spring. Watch for splits, edges coming away or growth in the joint.
Gaps, plants or missing sealant in a joint are worth getting looked at. Early work is quicker and leaves a better finish.
Ningwood: your questions answered
Can you do external mastic in Ningwood?
Yes, Ningwood is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or send us an email and let us know what needs doing, and we will give you a clear price.
Does the coastal weather in Ningwood affect outside sealant?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. The right product, a clean joint and the right depth all help it cope.
Do you hold any approvals?
Yes. We hold ARBOMaster approved applicator status and we are fully insured too.
Are you insured?
Yes, we’re fully insured.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
Do you seal joints where cladding meets other materials?
Yes. Materials like render, brick, metal and uPVC all move differently, so a flexible sealant is needed where they meet. We choose one that suits both surfaces.
Will the new joint stand out?
There’s a good range of exterior colours, including greys, browns, whites and stone tones. We pick the one that suits your wall best.
Will you leave a mess?
Tidy work is part of the job. We protect what’s around the joints, and the area is left clean when we finish.
The process
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself generally takes anything from a few hours to several days, depending on the building, depending on the amount of work. For a village or hamlet like Ningwood, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- The old mastic and anything lodged in the joint is removed.
- The joint faces are cleaned and primed where the sealant needs it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
How to prepare
- Keep children and pets away from the work area
- Let us know about parking restrictions
- Tell us about any previous sealing or DIY attempts
