FAQs for Hollingbury
Does the coastal weather in Hollingbury affect outside sealant?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Do you work for landlords with property near Moulsecoomb station?
Yes, we work for landlords and letting agents. You can call 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before we start.
Is the work guaranteed?
Yes, always. Each job is guaranteed for twelve months, wherever you are.
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.
Will you leave a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
How long before the joint can be used?
Different products cure at different speeds, so please follow the time we give you when we finish.
Are you insured?
Yes. We’re fully insured.
Can you work on commercial sites?
Yes. Larger jobs can be planned room by room or area by area to suit the site.
External mastic in Hollingbury, done properly
For buildings in Hollingbury, we reseal external joints of all kinds, from brick movement joints to cladding panels. Every joint gets the same careful preparation: clean joint faces and the right depth. We work on brickwork movement joints, copings & trims and joints between brick and frames, and people most often call us about movement joints with cracked, split or missing sealant and rain getting behind render or cladding at a joint.
Outbuildings, garages and conservatories around homes in places like Hollingbury add more joints to look after. Gutter ends, garage door frames and the joints where an extension meets the house are typical spots for leaks.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

When it isn’t the sealant
It helps to know what we can’t do:
- Rising or penetrating damp from elsewhere in the wall
- Loose or hollow render, which needs re-rendering
- Adding movement joints to masonry that has none
If in doubt, call 0345 464 0079 or email us and we’ll say what we think.
Where we work in Hollingbury
- Concrete & block
- Render & cladding joints
- Copings & trims
- Joints between brick and frames
- Brickwork movement joints
- Façade panels
What the job involves on each surface
Concrete and blockwork
The face of concrete or block is often dusty, so preparation is key. We prime where the sealant needs it before sealing.
Cladding and façade panels
Panels heat up and cool down quickly, so the joints work hard every day. The sealant is chosen with that in mind.
DIY sealant or a professional job?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
What we do, step by step
A visit follows a simple pattern: we look at the joints together, protect the area around them, carry out the job and clear up. Most jobs take a few hours to a few days, depending on the length of joint and the access. Parking around Hollingbury is normally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- Each joint is checked and the colour of the new sealant agreed.
- 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.
- We gun in low-modulus sealant and tool it neatly.
Getting ready for the visit
- Tell us about any previous sealing or DIY attempts
- On commercial sites, let us know about site rules
- Keep pets and children clear of the area while we work

Landlord and commercial work in Hollingbury
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.
What affects the cost of external mastic
We do not publish a price list. The quote depends on:
- Access and height
- Whether old sealant or filler has to be cut out
- The product the joint needs
- The number of rooms or windows
The cost reflects the work involved, not guesswork. That is why we ask about the job first and agree the price before starting.
What to tell us for a quote
Photos by email are helpful but not essential. Try to tell us:
- How we’d reach the joints
- Where the property is
- The rough size of the job
- If someone has resealed it before
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and add pictures by email if you can.

Do you need external mastic in Hollingbury?
UV, rain and frost all age exterior sealant. Over the years it hardens, cracks on the surface and loses its give, so the joint eventually tears or comes away from one side.
These are the problems we are asked about most:
- Cracked joints where brick meets render or frames
- Movement joints with cracked, split or missing sealant
- Rigid filler in a joint that should flex
- Rain getting behind render or cladding at a joint

Walls and rooflines in Hollingbury
Hollingbury is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. With historic houses such as Preston Manor & Gardens (about 1.4 miles south-west) nearby, there’s older building stock in the area around Hollingbury 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.
Historic houses such as Preston Manor & Gardens, about 1.4 miles south-west, show how far back building around Hollingbury goes, and older homes nearby need a sealant that suits their walls.
