Outside joints around Pound Hill
Crawley, which Pound Hill is part of, is one of England’s post-war new towns. Many homes date from the post-war decades and were built in phases, so neighbouring houses often have rooflines and wall joints of the same age, wearing out at the same time. With historic houses such as Gravetye Manor (about 4.6 miles south-east) nearby, there’s older building stock in the area around Pound Hill as well as newer homes. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material.
For site and facilities teams at buildings such as Pound Hill Infant Academy, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. For an older house near a landmark such as St Barnabas', the joints between older walls, newer extensions and the roofline need a sealant that can move.

How we handle external mastic in Pound Hill
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, so it bonds to the two sides only and can stretch. Typical jobs include plants rooting in failed movement joints and failed seals between different materials, across brickwork movement joints, façade panels and copings & trims.
Outbuildings, garages and conservatories around homes in places like Pound Hill add more joints to look after. Leaks normally start at a gutter end, a garage door frame or where an extension meets the house.
All our work is covered by a 12-month guarantee.

Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Act on the first splits you see
- Keep high-pressure jets off the joints
- Check the sealant is paintable before painting near it
- Walk round the building once a year and look at the joints
Avoid pressure-washing straight into the joints. High-pressure water can lift the edges.
Act while the splits are small. Then it’s a straightforward cut-out and reseal before water has had years to get in.
Work for landlords, hotels and businesses
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.

How the job changes by surface
Joints between dissimilar materials
Wherever two materials meet, they move differently. We seal the joint with a flexible exterior sealant so the movement is taken up.
Copings and trims
Coping and trim joints face rain and sun head on. Each is resealed with a weatherproof, flexible sealant.
Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
The process
There’s no need to move everything out before we come, just the space around the work. Everything nearby is protected, and the job takes anything from a few hours to several days, depending on the building for a typical job. In a smaller place like Pound Hill, 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.
- We look at every joint and agree a colour to suit the wall.
- We take out the old sealant until the faces are sound.
- Backing rod goes in so the sealant can stretch between the two faces.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Try not to wet indoor joints just before the visit
- Tell us about access, such as stairs, a lift or high-level joints

Advice
Common problems we fix in Pound Hill
Using the wrong sealant is another common reason. A high-modulus or general-purpose sealant can be too rigid for a busy joint, and it tears off the sides.
Keep an eye out for any of the following:
- Water getting into walls through failed joints
- Joints pointed up with cement by mistake
- Weeds or debris growing in open joints
- Cracked joints where brick meets render or frames
Letting a property close to Three Bridges station? Then split movement joints are easy to miss on a rental until damp shows inside.

Common questions in Pound Hill
Do you cover smaller places like Pound Hill?
Yes, Pound Hill is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
I let a flat near Three Bridges station. Can you help?
Yes, we work for letting agents and landlords. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear quote.
Can you match the colour of my brickwork?
The aim is a neat, even joint in a colour that suits the wall. We will talk through colour options before we start.
Do you work for hotels and businesses?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. We can talk about working times when we quote.
Will the old sealant be removed?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
What do you need from me for a quote?
The location, the problem and the rough size of the job. Photos by email help too.
Can I do it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
How do you reach high-level joints?
That depends on the building and the joints. Where joints can be reached safely, we will do them. Give us some details and we will confirm the access.
