About our window mastic in Terrick
Most frames have an outside joint and an inside one. The external joint is the weather seal; inside, the joint between frame and plaster stops draughts and tidies the reveal. We seal one or both, depending on what’s needed. We work on patio & French doors, aluminium frames and timber windows & doors, and common reasons people get in touch are rushed sealant from a window installation and sealant in the wrong colour for the frame.
Around Terrick, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

What affects the quote in Terrick
For a quick quote, just ask. What matters most is:
- The number of rooms or windows
- Any working-time requirements on site
- The old material and how stubborn it is
- The type of sealant required
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are not sure whether it needs doing, call 0345 464 0079 or email us for an honest opinion and a quote.

For landlords and businesses
Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
Why deal with it now?
Getting a straight, even bead on an outside frame takes practice, especially on upper floors. We cut out properly, back deep gaps and tool every joint neatly, in a sealant suited to the wall. In a small place like Terrick, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first and agree the price before starting.
What you get with us
- A sealant colour to suit the surroundings
- Tidy, careful work
- A choice of colours where the product allows
- Trusted Arbo and Everbuild sealants

How it works
We keep the work tidy and contained to the area we are working on, so you can get on with your day. The job usually takes a morning for a couple of windows and a door.

- We start by checking each window and door with you.
- The old mastic is cut out and the surfaces cleaned back.
- Where gaps are deep, backing rod goes in first.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- Every joint is checked before we leave.

Advice
When something else is needed
To be straight with you, some problems need a different trade:
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Faulty window hardware
- A frame that has rotted at the joint
Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly.
Surfaces we seal

When to call us in Terrick
Mastic ages in the weather. UV light hardens the outside of the bead, and over the years it loses its give, cracks and comes away.
Most people get in touch after spotting one of these:
- White mastic on grey or black frames
- Mastic that’s falling out in pieces
- Rain getting in at the frame or under the sill
- Gaps where the sill meets the wall
Schools such as John Colet School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

What window mastic looks like in Terrick
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you let a flat or house near Little Kimble station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. Homes close to Church of St Peter and St Paul include some older properties, and the joint between an old wall and a newer frame is normally the first place rain gets in.

How the job changes by surface
Timber windows & doors
Wood swells when it’s wet and shrinks when it dries, so a flexible sealant is essential. The paint or stain needs to be sound where the sealant meets it.
uPVC windows
uPVC expands and contracts noticeably with temperature, so the joint needs a low-modulus sealant that stays flexible. We match white, brown, anthracite grey and black frames.
