Different surfaces, different methods

Concrete and blockwork
The face of concrete or block is often dusty, so cleaning and priming matter. We prime where the sealant needs it.
External mastic for homes and businesses in Fawley Bottom
Getting the depth right is half the job. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, leaving it bonded to two faces so it can move with the wall. Typical jobs include failed seals between different materials and sealant that has lost its bond to the brick or render, on joints between brick and frames, copings & trims and brickwork movement joints.
Older homes in small places like Fawley Bottom may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

How to look after the new joints
Looking after new joints is easy, and it makes a real difference:
- Walk round the building once a year and look at the joints
- Ask before painting over external sealant
- Act on the first splits you see
- Show decorators and builders where the movement joints are
Keep the joints clear of soil, plants and climbing growth. Damp material against the sealant shortens its life.
Act while the splits are small. At that stage it’s a simple cut out and reseal before water has had years to get in.
What affects the quote in Fawley Bottom
Some jobs are bigger than they look, and some smaller. The main factors:
- Whether old sealant or filler has to be cut out
- Working hours on commercial sites
- Any mould that needs treating
- The product the joint needs
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts, so you know where you stand.

Why act early in Fawley Bottom
Pointing a movement joint with mortar might seem a neat fix, but it stops the joint moving. The wall then cracks somewhere else. The correct repair is a flexible sealant with the right backing. In a small place like Fawley Bottom, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Leaving a failed joint usually makes the job bigger, not smaller. If you are unsure, ring 0345 464 0079 or email us and we will give you an honest view and a quote.

Your questions about external mastic in Fawley Bottom
Is Fawley Bottom within the area you cover?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Is Fawley Bottom in your area for external mastic?
Yes. We work across London and the South East, and Fawley Bottom is part of that. Just ring 0345 464 0079 or email us with a few details of the job.
Do I need to be at home?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
What colours does the sealant come in?
Exterior sealants are made in a range of colours, from greys and browns to whites and stone shades. We choose the closest to your brick or render.
How do I get a quote for external mastic in Fawley Bottom?
Size, access and the old material all affect the cost. Ask us for a quote and we will talk you through it.
When will the joints need doing again?
It varies with how exposed the wall is and how much the joint moves. Look for splits, hardening or edges coming away and have them redone then.
What do you put in the joint?
Products from Arbo and Everbuild, among others, picked for each joint. We explain the product when we quote.
Can new sealant go over the old?
No. New silicone won’t bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
The process
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for a handful of joints, longer for a whole elevation and we leave things clean and tidy. Somewhere as small as Fawley Bottom, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- We cut out the failed sealant and rake out any dirt or growth.
- We clean both faces of the joint and prime them where the product calls for it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
How to prepare
- Let us know about stairs, lifts or work at height
- For indoor joints, keep the area dry beforehand if you can
- Tell us about any water getting in

Related advice
Do you need external mastic in Fawley Bottom?
Weeds, moss and debris in a joint are a sign the sealant has gone. Dirt and roots then trap moisture in the joint and speed up the damage.
Keep an eye out for these signs:
- Water getting into walls through failed joints
- Gaps where render, brick and frames meet
- Panel joints letting water in
- Sealant that has lost its bond to the brick or render
Homes close to St Mary the Virgin's Church include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.
What your quote should include
- Who does the work, and how experienced they are
- What product goes in the joint
- Is VAT in the price?
- Are they insured?
