External mastic in Sutton Valence
Many failed façade joints only get noticed once there’s a stain or a damp patch inside. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant in a colour to suit. If you are dealing with damp patches traced to an open external joint and joints where the bead has come unstuck, we can help.
In a village or hamlet like Sutton Valence, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.

FAQs for Sutton Valence
Will you come out to Sutton Valence?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
I let a flat near Staplehurst station. Can you help?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or email us and tell us about the property, and we’ll send you a clear quote.
Can you seal over the old sealant?
No. New silicone will not bond to old silicone, and it traps any mould or water underneath. It all has to come out first.
When is the sealant fully cured?
Cure times vary by product and the conditions. Before we leave, we’ll tell you the cure time.
Do you do commercial work?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. We can talk about working times when we quote.
Is it messy?
Not at all. The area is protected while we work and cleaned up afterwards.
Do I need to be at home?
That depends on where the joints are. For work indoors, someone needs to let us in.
Should I try DIY first?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
External mastic in Sutton Valence: local notes
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Stoneacre (about 2.8 miles north) nearby, there’s older building stock in the area around Sutton Valence as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
For landlords with property near Staplehurst station, split movement joints are easy to miss on a rental until damp shows inside. Managing a site like Sutton Valence Primary School? Then larger buildings have long runs of movement joint that eventually need resealing.

How it works
When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours to a few days, depending on the length of joint and the access. In a small place like Sutton Valence, access is usually the main thing to plan. 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.
- We cut out the old mastic and rake out anything in the joint.
- Joint faces are cleaned back and primed if the sealant needs 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
- Where the joints are inside, avoid wetting them before we arrive
- Tell us if parking is tricky
- Tell us about any previous sealing or DIY attempts

When it isn’t the sealant
Sealant is not the answer to every problem, and we will tell you before any work starts. It will not solve:
- Cracking across the wall rather than at a joint
- Movement that is more than a sealant joint can take
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
Not sure which it is? You can ring 0345 464 0079 or email us and we will tell you honestly before you book.
Surfaces we seal
- Joints between brick and frames
- Brickwork movement joints
- Façade panels
- Concrete & block
- Render & cladding joints
- Copings & trims
Signs you need external mastic in Sutton Valence
Buildings move more than people expect. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. The sealant in the movement joints takes that strain.
Keep an eye out for these signs:
- Sealant that has lost its bond to the brick or render
- Brick movement joints where the sealant has split
- Leaking joints around cladding and façade panels
- Water getting into walls through failed joints
In the older streets around Church of St Mary, older walls, gutters and the joints where extensions meet them need a flexible sealant.
What to look for in a quote
- Which colour the sealant will be
- What happens if the job turns out different
- Whether they’re fully insured
- Whether the sealant suits the joint
Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Act on the first splits you see
- Deal with leaking gutters that soak the joints below
- Keep soil, plants and ivy away from the joints
- Never let anyone fill a movement joint with mortar
Follow the cure time we give you before the joint is knocked or disturbed. The surface skins over quickly, but full cure takes longer.
Leave a failed movement joint and water keeps getting into the wall. That can lead to damp patches, staining and frost damage, all bigger jobs than a reseal.
What affects the cost of external mastic
There’s no set price list, because jobs vary so much. What we look at:
- Whether there’s mould to deal with
- When we can work, for business premises
- Whether old sealant or filler has to be cut out
- Access and height
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
Asking for a quote
What to tell us when you ask for a quote:
- The address or postcode of the job
- The problem you’ve noticed
- The type of property
- Roughly how big the job is
For a quick quote, get us on the phone, or email us if that is easier. Describe what needs sealing and we will explain what’s involved.
Should I try it myself first?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Surface by surface
Joints between dissimilar materials
Brick against render, concrete against metal, stone against timber: every change of material is a joint. We seal the joint with a flexible exterior sealant.
Copings and trims
A failed coping joint lets water into the top of the wall. Resealing them is a small job that protects a lot.
