What we do, step by step
Most of a good job is in the preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. In total, it usually takes a few hours to a few days, depending on the length of joint and the access. Somewhere as small as Sibford Ferris, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- We fit closed-cell backing rod to control the depth.
- We apply the sealant, tool it and check the whole run.
Preparing for the visit
- For business premises, tell us about site rules or sign-in
- Mention if the joints have been sealed before
- Let us know about stairs, lifts or work at height

How we handle external mastic in Sibford Ferris
Low-level joints can normally be done from the ground. For joints higher up, give us some details of the building and we’ll confirm what’s needed to reach them safely. If you have panel joints letting water in and sealant that has lost its bond to the brick or render, we can put it right, on copings & trims, brickwork movement joints and joints between brick and frames alike.
In a village or hamlet like Sibford Ferris, 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.
All of our work is guaranteed for twelve months, in Sibford Ferris and everywhere else we cover.

Keeping the joints in good condition
Simple care keeps the joints in good condition. We recommend:
- Deal with leaking gutters that soak the joints below
- Check the sealant is paintable before painting near it
- Never let anyone fill a movement joint with mortar
- Get split or bare joints resealed while the damage is small
Look over the joints once a year, ideally after winter. Splits, gaps at the edges or plants in the joint are early warning signs.
If you can see gaps, plants or bare sections in a joint, have it checked. Earlier resealing means a smaller job and a better result.

Common questions in Sibford Ferris
Is external mastic in Sibford Ferris guaranteed?
All our work, in Sibford Ferris and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
Will you come out to Sibford Ferris?
Yes, Sibford Ferris is covered. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Can you quote for more than one area?
Yes. Just list everything you need and we’ll quote it together.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
How long will you be here?
As a guide, most jobs take a few hours for a handful of joints, longer for a whole elevation. Larger jobs naturally take longer, and we will say how long yours will take.
Is there any odour?
Sometimes, a little. Any smell clears as the sealant cures.
Can I do it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
Will the new joint stand out?
We choose a sealant colour to suit the brick, stone or render so the joint blends in. Exterior sealants come in a good range of colours.
Can I do it myself?
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.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
For landlords and businesses
Housing providers, facilities teams and property managers book us too. Several sites can go on one quote.
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
What we’re called out for in Sibford Ferris
The wrong product in a moving joint is a classic cause. A high-modulus or general-purpose sealant can be too rigid for a busy joint, and it tears off the sides.
Look out for these signs:
- Joints where the bead has come unstuck
- Weeds or debris growing in open joints
- Cracked joints where brick meets render or frames
- Damp patches traced to an open external joint
Homes close to Church of Holy Trinity include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.

- How the surfaces are prepared before sealing
- What happens if the job turns out different
- Whether you can choose the colour
- Whether all the old sealant comes out first
Outside joints around Sibford Ferris
With historic houses such as Broughton Castle (about 3.8 miles east) nearby, there’s older building stock in the area around Sibford Ferris as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
