Sand mastic for homes and businesses in Fawler
Sand mastic does not last for ever and gaps open up round the frame. Renewing it closes the gap so the surround looks right again. If you have old sand mastic that has cracked, crumbled or fallen out and draughts and rain around sash boxes, we can put it right.
Outdoor sealant needs dry, clean surfaces, so work on frames around Fawler is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
Whatever the size of the job, you get the same 12-month guarantee.

Do you need sand mastic in Fawler?
Shallow joints are a common cause. A thin layer does not hold well, which is why we pack deep voids first and get the depth right.
Look out for these signs:
- Weathered mastic on the most exposed windows
- Patchy fillers round a sash window
- Draughts and rain around sash boxes
- Mastic that needs renewing before redecorating
If you look after a building such as Finstock Church of England Primary School, the mastic around its windows and doors needs looking after like any other building’s.

What happens if it’s left?
A silicone bead can be quicker, but it can look wrong on a period surround. Sand mastic is the traditional material and blends with the stone or brick. Around Fawler, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
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, ring 0345 464 0079 or drop us an email for an honest opinion and a quote.

What happens on the day
On the day, we look over the joints with you first. Surfaces next to the work are protected before any work begins. The work generally takes a few hours per window, depending on the condition of the joints. In a small place like Fawler, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check the window surrounds and agree which joints need renewing.
- 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.
How to prepare
- Plan for the work area to be out of bounds to pets and children
- Let us know if you’ve seen damp or leaks
- Move anything stored near the joints

How the job changes by surface
Period and listed homes
Sand mastic is the like-for-like choice for many period homes. On listed buildings, check with your planning authority first.
Brick reveals
An open joint at a brick reveal lets weather in. Renewing the mastic closes it.
What affects the quote in Fawler
We quote each job individually. This is what makes a difference:
- Whether the work is at height
- The old material and how stubborn it is
- The type of sealant required
- Any working-time requirements on site
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
What we need to know
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- If it’s domestic, commercial or a hotel
- What the problem is, such as mould, gaps, leaks or cracking
- How we’d reach the joints
- A few photos by email, if you can
We don’t publish a price list, as no two jobs are quite the same. Instead, we give you a clear price for your job. To get started, phone 0345 464 0079 or drop us an email.
Other services in Fawler
Fawler homes and the weather
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Blenheim Palace (about 4.4 miles east) are a reminder that the area around Fawler has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Rented homes near Finstock station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out. For an older house near a landmark such as Church of the Holy Trinity, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Aftercare tips
After the cure time, these simple habits help:
- Renew mastic before redecorating the windows
- Avoid heavy scraping on the mastic joint
- Do not run silicone over sand mastic
- Don’t paint over the new mastic
Make sure water drains away from the window surround. Water sitting against the mastic shortens its life.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.
