External mastic in Northchapel
Low-level joints can normally be done from the ground. Where joints are higher up, tell us about the building when you get in touch and we’ll confirm what’s needed to reach them safely. If you are dealing with damp patches traced to an open external joint and panel joints letting water in, we can put it right.
External sealant needs dry, clean surfaces, so work around Northchapel is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
Big or small, you get the same one-year guarantee.

What happens if it’s left?
The longer a joint stays open, the more water the wall takes in. Wet masonry is more easily damaged by frost near the open joint, so the problem grows beyond the joint itself. Older cottages and farmhouses around Northchapel can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or drop us an email and we will talk you through it.

External mastic in Northchapel: local notes
With historic houses such as Petworth House (about 4.9 miles south) nearby, there’s older building stock in the area around Northchapel 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. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Homes close to The Parish Church of St Michael include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep. For landlords with property near Haslemere station, outside joints that have cracked can let damp into a rental, so check them between lets.

DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

What sealant work cannot fix
New sealant cannot fix everything, and we’d rather say so up front. Sealant will not put right:
- Walls that need new movement joints cut into them
- Subsidence or other structural problems
- Render that’s blown, hollow or coming away
If you are not sure, just ring 0345 464 0079 or email us and we will give you a straight answer before booking.
Surfaces we seal
- Render & cladding joints
- Concrete & block
- Brickwork movement joints
- Joints between brick and frames
- Façade panels
- Copings & trims
Common problems we fix in Northchapel
If plants are growing out of a joint, the sealant has generally failed or was never there. Dirt and roots then trap moisture in the joint and speed up the damage.
Keep an eye out for any of the following:
- Moss and dirt in joints with no sealant left
- Joints pointed up with cement by mistake
- Sealant that has lost its bond to the brick or render
- Leaking joints around cladding and façade panels
Schools such as Northchapel Community Primary School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing.

What we do, step by step
Most of a good job is in the preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it usually takes anything from a few hours to several days, depending on the building. For a village or hamlet like Northchapel, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- 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.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- Mention if the joints have been sealed before
- Tell us about any water getting in

Questions from Northchapel
Can you help a landlord with a rental near Haslemere station?
Yes, rental work is part of what we do. You can phone 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Will you come out to Northchapel?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Are you ARBOMaster approved?
Yes. We are an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
Should I point up the gap in my brickwork?
No. Rigid materials cannot move with the wall. If it has already been filled, we can normally cut it out and reseal it.
Do the sealants smell?
Possibly a little. Any smell clears as the sealant cures.
Why do you put foam in the joint first?
Closed-cell backing rod sets the depth of the sealant and stops it sticking to the back of the joint. Then the sealant bonds to two faces and can move.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done.
Do you seal joints where cladding meets other materials?
Yes. Different materials move at different rates, so a flexible sealant is needed where they meet. The sealant is matched to both sides.
