External mastic for homes and businesses in Crockerhill
For buildings in Crockerhill, we reseal external joints of all kinds, from brick movement joints to cladding panels. Every joint gets the same careful preparation: clean, sound faces and a controlled depth. We work on brickwork movement joints, copings & trims and concrete & block, and people most often call us about water getting into walls through failed joints and sealant pulling away from one side of the joint.
Somewhere as small as Crockerhill, homes and farm buildings often face open ground, where walls and rooflines take the weather head on. Gutter joints and wall joints there need a sealant that can flex and stay put.
We stand behind the work with a one-year guarantee, so you’re not left on your own once the job is done.

Common problems we fix in Crockerhill
If plants are growing out of a joint, the sealant has usually failed or was never there. Dirt and roots then trap moisture in the joint and speed up the damage.
The problems people usually mention when they call are:
- Movement joints with cracked, split or missing sealant
- Gaps where render, brick and frames meet
- Plants rooting in failed movement joints
- Water getting into walls through failed joints
Managing a site like The Henry Cort Community College? Then larger buildings have long runs of movement joint that eventually need resealing.

Crockerhill questions
I let a flat near Fareham station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just phone 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear quote.
Do you cover smaller places like Crockerhill?
Yes. Crockerhill is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
How long does the job take?
It depends on the size of the job, but most jobs take a few hours for a handful of joints, longer for a whole elevation. We will give you a better idea when we quote.
Which products do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
What information do you need?
Only a few details: where it is, what you’ve noticed and how we reach it. Then call 0345 464 0079 or send us an email.
Is the work guaranteed?
Yes. Every job comes with a 12-month guarantee.
Does someone need to be in?
It depends on the job. For work indoors, someone needs to let us in, and for outside work we will agree access with you when we book.
Do you remove the old sealant?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
What sealant work cannot fix
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Failed render or damaged cladding panels
- Adding movement joints to masonry that has none
- Structural movement, which needs a surveyor or engineer
If you are not sure, just ring 0345 464 0079 or email us and we will give you a straight answer before you book.
Joints and surfaces we work on
- Render & cladding joints
- Joints between brick and frames
- Concrete & block
- Façade panels
- Brickwork movement joints
- Copings & trims
Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Point out the joints to other trades
- Walk round the building once a year and look at the joints
- Deal with leaking gutters that soak the joints below
- Get split or bare joints resealed while the damage is small
Only paint over the joint if we have confirmed the sealant can take paint. Many exterior sealants are not designed to be painted and spoil the finish.
Small splits are the time to act. At that stage it’s a simple cut out and reseal before water has had years to get in.
Walls and rooflines in Crockerhill
Crockerhill is within about 3 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on movement joints and outside wall joints, especially on the side facing the sea. London and the South East are among the drier parts 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. Homes close to Church of St Nicholas include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.

Around Crockerhill

Leave it or put it right?
Mortar or ordinary filler might look like a quick way to close an open joint, but it locks the joint solid. The wall then cracks somewhere else. The correct repair is a flexible sealant with the right backing. Older cottages and farmhouses around Crockerhill can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
The cost reflects the work involved, not guesswork. That’s why we ask about the job first and agree the price before starting.

What affects the cost of external mastic
The price is agreed before any work begins. It’s based on:
- The size of the job
- When we can work, for business premises
- Whether old sealant or filler has to be cut out
- How many rooms, windows or areas are involved
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we’ll explain what it covers.

A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- How we’d reach the joints
- The rough size of the job
- Where the property is
- Pictures of the joints, sent by email
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email pictures if that’s easy.
What we do, step by step
There’s no need to move everything out before we come, just the space around the work. We protect the rest, and the job takes a few hours for a handful of joints, longer for a whole elevation in most cases. Somewhere as small as Crockerhill, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
How to prepare
- Let us know about stairs, lifts or work at height
- Tell us if parking is tricky
- Where the joints are inside, avoid wetting them before we arrive
