What happens if it’s left?
Done well, a resealed joint is a neat, straight line that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner so it’s worth doing right. Older cottages and farmhouses around Crowhurst Lane End can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

FAQs for Crowhurst Lane End
Can you help a landlord with a rental near Godstone station?
Yes. We work for landlords and agents as well as householders. You can ring 0345 464 0079 or drop us an email with the details for a clear quote.
Do you cover smaller places like Crowhurst Lane End?
Yes. Crowhurst Lane End is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
How do you reach high-level joints?
Each building is different. Send us pictures and a rough idea of the height, and we’ll confirm what access is needed.
How long will you be here?
Most jobs take a few hours to a few days, depending on the length of joint and the access. We’ll confirm how long when we quote.
Which products do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We will tell you what we are using and why.
Can you seal joints between render and window frames?
Yes. We cut out the old sealant, prepare both faces and reseal with a flexible exterior product. The colour is chosen to suit.
Will you leave a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
Is it OK to fill a movement joint with cement?
No. Cement or mortar cannot stretch, so the joint stops doing its job. If it has already been filled, we can usually cut it out and reseal it.
Can I do it myself?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
A DIY attempt does not rule out a professional job. We cut it out and start again.
What external mastic looks like in Crowhurst Lane End
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. With historic houses such as Titsey Place (about 4.6 miles north-east) nearby, there’s older building stock in the area around Crowhurst Lane End 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 an older house near a landmark such as Church of St George, an extension built onto an older house moves differently, and the joint between them takes the strain. Managing a site like St Stephen's CofE Primary School? Then larger buildings have long runs of movement joint that eventually need resealing.

What we can’t put right
We’d rather tell you now than do work that will not last, so these are the limits:
- Walls that need new movement joints cut into them
- Subsidence or other structural problems
- Loose or hollow render, which needs re-rendering
Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly.
Joints and surfaces we work on
- Façade panels
- Copings & trims
- Render & cladding joints
- Concrete & block
- Brickwork movement joints
- Joints between brick and frames
Looking after it afterwards
Simple care keeps the joints in good condition. Our advice:
- Fix overflowing gutters above sealed joints
- Tell anyone working on the walls about the movement joints
- Get split or bare joints resealed while the damage is small
- Keep high-pressure jets off the joints
Keep the joints clear of soil, plants and climbing growth. Damp material against the sealant shortens its life.
Leave a failed movement joint and water keeps getting into the wall. Over time it can mean damp inside, stained render or frost-damaged brick which cost more to put right than the joint.

Other services in Crowhurst Lane End
Do you need external mastic in Crowhurst Lane End?
Many joints fail because they were sealed too deep or with nothing behind them. If the sealant sticks to the back as well as the sides, it can’t stretch and rips as the joint opens.
The problems people normally mention when they call include:
- Weathered mastic that no longer stretches
- Sealant that has lost its bond to the brick or render
- Brick movement joints where the sealant has split
- Water getting into walls through failed joints
For landlords with property near Godstone station, split movement joints are easy to miss on a rental until damp shows inside.
