External & façade joints in Catisfield, Hampshire
Problem with your movement joints in Catisfield? We cut out the old, prepare the joints and apply the right sealant, and the work is guaranteed for a year.
- Brick movement joints where the sealant has split
- Joints where the bead has come unstuck
- Failed sealant between panels on a façade
Why act early in Catisfield
The longer a joint stays open, the more water the wall takes in. In cold weather, frost can damage wet brick and render around the joint, so the damage spreads beyond the joint. Around Catisfield, water from a failed joint in an older home can soak into timber and plaster, and that is a much bigger job than renewing the sealant.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs. Ask us for a quote and we will explain what it covers.
Why book with us
- Quality sealants from Arbo and Everbuild
- Sanitary silicone with an anti-fungal additive in wet areas

External mastic for homes and businesses in Catisfield
On houses, flats and commercial buildings across Catisfield, we reseal joints in brickwork, render, cladding and façade panels. Every joint gets the same careful preparation: clean, sound faces and a controlled depth. If you’re dealing with weeds or debris growing in open joints and rigid filler in a joint that should flex, we can help.
In a smaller place like Catisfield, some homes face open ground, and walls and rooflines facing the weather take the worst of it. That is where gutter joints and wall joints tend to fail first.
Whatever the size of the job, you get the same 12-month guarantee in Catisfield and across Hampshire.

Surface by surface
Joints between dissimilar materials
Brick against render, concrete against metal, stone against timber: every change of material is a joint. We seal the joint with a flexible exterior sealant.
Copings and trims
A failed coping joint lets water into the top of the wall. Resealing them is a small job that protects a lot.
Outside joints around Catisfield
Catisfield 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. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For landlords with property near Fareham station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. Managing a site like Ranvilles Infant School? Then its movement joints, gutters and trims need looking after like any other building’s.

Catisfield: your questions answered
I let a flat near Fareham station. Can you help?
Yes. We work for landlords and letting agents as well as homeowners, and several properties can be quoted together. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we will give you a clear price.
Does the coastal weather in Catisfield affect outside sealant?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
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. That way it bonds to the two sides only and can stretch.
Are you an approved applicator?
Yes. We’re approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.
Should I try DIY first?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Which products do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Is there a guarantee?
Yes. Every job comes with a one-year guarantee.

There is not much for you to do on the day. Show us the job and we’ll take it from there. The job generally takes anything from a few hours to several days, depending on the building from start to finish. A visit to Catisfield is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Backing rod goes in so the sealant can stretch between the two faces.
- Primer is applied wherever the sealant needs it.
- We gun in low-modulus sealant and tool it neatly.
How to prepare
- Try not to wet indoor joints just before the visit
- Let us know about stairs, lifts or work at height
- Move anything stored near the joints
How to get a quote
Getting a quote is simple: let us know the job and the location and its rough size. Photos by email help us understand the job, and we will take it from there.
Advice
How to look after the new joints
A little care helps the new joints last. We recommend:
- Keep movement joints as flexible joints, not mortar
- Get split or bare joints resealed while the damage is small
- Keep water from gutters off the wall
- Clear growth from the base of walls and joints
Only paint over the joint if we’ve confirmed the sealant can take paint. Many exterior sealants are not designed to be painted, and paint can crack as the joint moves.
If you can see gaps, plants or bare sections in a joint, have it checked. Early work is quicker and leaves a better finish.
When it isn’t the sealant
It helps to know what we can’t do too:
- Walls that need new movement joints cut into them
- Render that’s blown, hollow or coming away
- Cracks in the bricks or render themselves, away from the joints
If you are not sure, just phone 0345 464 0079 or send us an email and we’ll give you a straight answer before you book.

- Copings & trims
- Render & cladding joints
- Façade panels
- Brickwork movement joints
- Concrete & block
Common problems we fix in Catisfield
Weeds, moss and debris in a joint are a sign the sealant has gone. Roots and dirt hold water against the wall and make things worse.
Common reasons people contact us are:
- Old sealant gone brittle and cracked
- Cracked joints where brick meets render or frames
- Moss and dirt in joints with no sealant left
- Joints where the bead has come unstuck
For an older house near a landmark such as Church of St Peter, older walls, gutters and the joints where extensions meet them need a flexible sealant.
Questions to ask before booking
- Whether they seal over old material or remove it
- Whether VAT is included
- Whether they’re fully insured
- What happens if they find a problem under the old sealant
DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
