What we do, step by step
Good joint work is mostly preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours to a few days, depending on the length of joint and the access. Somewhere like Warren Corner needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- Old sealant and any debris are cut and raked out.
- We clean both faces of the joint and prime them where the product calls for it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Before we arrive
- On commercial sites, let us know about site rules
- Clear items away from the joints we’re working on
- For indoor joints, keep the area dry beforehand if you can

How we handle external mastic in Warren Corner
Getting the depth right is half the job. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, so it bonds to the two sides only and can stretch. Typical jobs include weathered mastic that no longer stretches and damp patches traced to an open external joint, on render & cladding joints, brickwork movement joints and joints between brick and frames.
In a village or hamlet like Warren Corner, older cottages and farm buildings often stand in the open, where walls and rooflines take the weather head on. Joints on those walls need a sealant that moves with the building and stays in place.
Whatever the size of the job, you get the same one-year guarantee.

What else we do in Warren Corner
Work for landlords, hotels and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can go on one quote.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Fix overflowing gutters above sealed joints
- Wash walls gently around the sealant
- Get split or bare joints resealed while the damage is small
- Look over the joints every year, ideally after winter
Make sure anyone working on the wall later knows where the movement joints are. They must stay as flexible joints, never rendered or pointed over.
A joint that has stopped moving pushes the movement elsewhere, often as cracks near the joint. Resealing it early helps prevent that.
DIY sealant or a professional job?
Too much sealant is as bad as too little. 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. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
How we quote for external mastic
There’s no set price list, because no two jobs are the same. What we look at:
- How easy the joints are to reach
- The number and length of the joints
- The product the joint needs
- Mould in or behind the old joints
Combining jobs into one visit is normally more efficient than separate visits. We will give you a clear quote for the lot.
Asking for a quote
You don’t need to know the technical terms. It helps if you can tell us:
- Photos by email, if that’s easy
- The rough size of the job
- The problem you’ve noticed
- How we’d reach the joints
Asking for a quote is easy: tell us what needs doing and where, and roughly how big it is. A few photos by email make the job easier to understand.
What we’re called out for in Warren Corner
The wrong product in a moving joint is a classic cause. A stiff, general-purpose sealant can’t cope with a joint that moves a lot, and it tears off the sides.
Look out for any of the following:
- Leaking joints around cladding and façade panels
- Movement joints filled with mortar instead of sealant
- Moss and dirt in joints with no sealant left
- Rain getting behind render or cladding at a joint
Rented homes near Farnham station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.
What your quote should include
- Whether the sealant suits the joint
- Who turns up on the day
- The length of the guarantee
- Is the old sealant removed completely?
External mastic in Warren Corner: local notes
Historic houses like Farnham Castle (about 2 miles south-east) are a reminder that the area around Warren Corner has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth. 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 site and facilities teams at buildings such as Crondall Primary School, larger buildings have long runs of movement joint that eventually need resealing. If you live in an older home near St Mary's Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.
Warren Corner is about 3 miles south of Fleet, in Surrey. Warren Corner gets the same service as everywhere we cover: the old material taken out, joints prepared properly and a 12-month guarantee. Warren Corner is one of 395 towns and villages in Surrey we cover. Reading is on our list too, about 16 miles from Warren Corner.
Work in GU10 works the same way as everywhere else we cover. Local streets include Warren Corner and Redlands Lane. Close by, we work in Ewshot (1 mile north-east), Redlands (1 mile west), Dora's Green (1 mile south), Crondall (1 mile west) and Bowling Alley (1 mile west). Larger places within reach include Guildford (11 miles east), Woking (13 miles north-east), Camberley (8 miles north-east), Farnham (3 miles south-east), Frimley (7 miles north-east) and Haslemere (12 miles south-east).
What’s near Warren Corner
Locally, jobs take us to homes and businesses close to St Nicholas' School, The Windmill pub and Basingbourne Park. The closest station to Warren Corner is Farnham station, about 2.6 miles south-east of the centre. A little further out are Fleet Community Hospital (3.5 miles north) and Museum of Farnham (2.2 miles south-east). For a walk, there’s Aunt's Pool and Farnham Park.
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. Around Warren Corner, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, phone 0345 464 0079 or email us for an honest opinion and a quote.
