Twyford: your questions answered
Do you work for landlords with property near Twyford station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear price.
Is Twyford within the area you cover?
Yes. Twyford is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
How long does the job take?
A typical job takes anything from a few hours to several days, depending on the building, including preparation and clearing up. Your quote will say how long we expect yours to take.
Can new sealant go over the old?
No. New silicone will not bond to old silicone, and it traps any mould or water underneath. We remove it all first.
How often do external joints need resealing?
That depends on the wall, the weather and the movement. Look for splits, hardening or edges coming away.
Can you seal joints between render and window frames?
Yes. Materials like render, brick, metal and uPVC all move differently, so the joint between them must be flexible. The sealant is matched to both sides.
Should I point up the gap in my brickwork?
No. Mortar locks the joint solid, so the wall cracks somewhere else instead. It needs a flexible sealant over backing rod.
What colours does the sealant come in?
Exterior sealants are made in a range of colours, from greys and browns to whites and stone shades. We choose the closest to your brick or render so the joint doesn’t draw the eye.
What the job involves on each surface
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.
Cladding and façade panels
If the façade has a specified sealant, that’s what we use, or one the system allows. Send us any details you have about the façade.
Leave it or put it right?
An open joint keeps letting water into the wall with every downpour. Wet masonry is more easily damaged by frost near the open joint, so the damage spreads beyond the joint. Around Twyford, water from a failed joint in an older home can soak into timber and plaster, and that’s a much bigger job than renewing the sealant.
What you pay reflects the work, not guesswork. That is why we ask about the job first and send you a clear quote before we start.
Why book with us
- Any old sealant cut out fully, not covered over
- White, clear, grey or another colour, product permitting
- Experience in homes, commercial sites and hotels
- We leave the area clean and tidy
Do you need external mastic in Twyford?
The wrong product in a moving joint is a classic cause. A stiff, general-purpose sealant cannot cope with a joint that moves a lot, and it tears off the sides.
The problems people normally mention when they call include:
- Panel joints letting water in
- Joints where the bead has come unstuck
- Rain getting behind render or cladding at a joint
- Cracked joints where brick meets render or frames
For an older house near a landmark such as Church of St Mary, older walls, gutters and the joints where extensions meet them need a flexible sealant.
Before booking anyone
- Whether all the old sealant comes out first
- How long to leave it before use
- How the colour is chosen
- Whether the sealant suits the joint
When something else is needed
A few problems are outside what sealant work can do:
- Damp that is not coming from the joint
- Subsidence or other structural problems
- Walls that need new movement joints cut into them
If you’re not sure, just ring 0345 464 0079 or email us and we will give you a straight answer before you book.
Surfaces we seal
- Joints between brick and frames
- Copings & trims
- Concrete & block
- Façade panels
- Render & cladding joints
- Brickwork movement joints
Outside joints around Twyford
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.
Letting a property close to Twyford station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies. Managing a site like Polehampton Church of England Infant School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

How we quote for external mastic
There’s no set price list, because jobs vary so much. What we look at:
- Any working-time requirements on site
- Any mould that needs treating
- The type of sealant required
- How many rooms, windows or areas are involved
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
Asking for a quote
Before you ask for a quote, have a think about:
- Any access issues, like height or stairs
- The address or postcode of the job
- Any previous sealing or DIY work
- What the problem is, such as mould, gaps, leaks or cracking
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and add photos by email if you can.
What we do, step by step
The work is kept neat and contained to the joints we are treating, so you can get on with your day. Expect the work to take a few hours for a handful of joints, longer for a whole elevation, and we explain the cure time before we leave. Parking around Twyford is normally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
- The old mastic and anything lodged in the joint is removed.
- Both sides are cleaned back to sound material and primed if needed.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- A flexible exterior sealant is applied and tooled in a colour to suit the wall.
Before we arrive
- Clear items away from the joints we are working on
- Keep children and pets away from the work area
- Tell us if parking is tricky
