Sand mastic in Northington
Silicone on a period window often looks wrong and isn’t always the right material. Sand mastic is the traditional choice and we can swap the silicone for it. If you are dealing with window mastic to renew ahead of painting and weathered mastic on the most exposed windows, we can help, on brick reveals, stone surrounds and sash and case windows alike.
Homes in small places like Northington often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
All of our work is guaranteed for twelve months, in Northington and everywhere else we cover.

Aftercare tips
Looking after new joints is easy:
- Renew mastic before redecorating the windows
- Avoid heavy scraping on the mastic joint
- Make sure water runs off the sill
- Ask the planning authority about consent for listed or conservation-area homes
Keep gutters and sills clear so water runs away from the surround. Constant wetting wears the mastic faster.
Renewing mastic before redecorating saves doing it twice. Paint over cracked mastic only covers it up.
What the job involves on each surface
Brick reveals
An open joint at a brick reveal lets weather in. New mastic seals the gap.
Timber door frames
Sand mastic is used round timber door frames too. The method is the same as for windows.
What we are called out for in Northington
Most of it is simply age. Even well-laid mastic needs renewing in time, depending on exposure and upkeep.
Most people get in touch after spotting something like this:
- Gaps between timber frames and stone or brick
- Draughts and rain around sash boxes
- Modern sealant on a period surround
- Gaps round a timber door in stone or brick
In the older streets around Church of St John the Evangelist, the joint between an old wall and a newer frame is normally the first place rain gets in.
What to look for in a quote
- How much experience the applicator has
- How the joint is cleaned and prepared
- Which sealant they’ll use, and why
- Whether all the old sealant comes out first
What we do, step by step
Good joint work is mostly preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for a single window, longer for several. In a small place like Northington, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, we look at the surrounds with you and agree what needs doing.
- We rake out the old mastic and clean the joint.
- We pack any deep gaps so the mastic sits at the right depth.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any leaks or damp you’ve noticed
- Mention any sign-in or site rules at work premises

Quotes for sand mastic in Northington
There’s no set price list. The quote depends on:
- The number of rooms or windows
- When we can work, for business premises
- The amount of work
- Whether there’s mould to deal with
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 we need extra access for height. Your quote takes all of that into account.
What we need to know
To make quoting easier, let us know:
- Access, such as stairs, a lift or height
- Whether it has been sealed before
- The type of property
- Pictures of the joints, sent by email
Asking for a quote is easy: let us know what needs doing and where. A few pictures by email make the job easier to understand, and we will take it from there.
Why act early in Northington
If you’re redecorating, renew the mastic first. Paint over cracked mastic will not stop the gaps, and the new mastic is traditionally left unpainted. Older cottages and farmhouses around Northington can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re unsure, phone 0345 464 0079 or send us an email for an honest opinion and a quote.
