What the job involves on each surface
Timber door frames
Period doors in stone or brick openings are often pointed with sand mastic. The method is the same as for windows.
Stone surrounds
Stone openings are rarely perfectly straight, so the gap isn’t the same all the way round. Sand mastic is shaped by hand to suit.
Sand mastic for homes and businesses in Puttenham
Old sand mastic cracks, crumbles and falls out over time, leaving gaps round the window. Renewing it closes the gap and tidies the surround. Common call-outs are for open joints round the window box and draughty sash windows at the surround, on timber door frames, brick reveals and sash and case windows.
Mastic can only go onto a dry, clean joint, so window work in Puttenham is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
Whatever the size of the job, it’s backed by our one-year guarantee in Puttenham and across Surrey.

Frames and glazing around Puttenham
With historic houses such as Wanborough Manor (about 0.9 miles north-east) nearby, there’s older building stock in the area around Puttenham as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you look after a building such as Puttenham CofE Infant School, the mastic around its windows and doors needs looking after like any other building’s. For landlords with property near Wanborough station, older sash windows in a rental need their mastic kept sound to keep the weather out.

Common questions in Puttenham
Is Puttenham within the area you cover?
Yes, Puttenham is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Is Puttenham in your area for sand mastic?
Yes, Puttenham is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or send us an email and let us know what needs doing, and we will give you a clear price.
Can you replace silicone on a period window with sand mastic?
Usually, yes. With the silicone removed and the joint cleaned we point it with sand mastic.
Is there any odour?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Can you seal over the old sealant?
No, and we never do. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Do you offer different sealant colours?
In most cases you can choose. We will explain which colours are available and agree one before we start.
Is it worth trying it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Can landlords and businesses book you?
Yes. We work for homeowners, landlords, letting agents, businesses and hotels.
How we quote for sand mastic
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Whether old sealant or filler has to be cut out
- How many rooms, windows or areas are involved
- Any mould that needs treating
- How much there is to do
There are no prices on our website, because each job is priced on what it involves. For a quick quote, please phone 0345 464 0079 or email us and we will talk you through it.
What to tell us for a quote
When you call or email, it’s useful to know:
- Roughly how big the job is
- Pictures of the joints, sent by email
- If it’s domestic, commercial or a hotel
- What the problem is, such as mould, gaps, leaks or cracking
Getting a quote is simple: let us know the job and the location and its rough size. A few pictures by email make the job easier to understand, and we will come back to you with a quote.
DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out 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 fails, we can still redo it.
How the visit works
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The work itself takes anything from a few hours to a full day, depending on how many windows, including the tidy-up. Somewhere as small as Puttenham, access is often the only tricky part. 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.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us about any water getting in
- Mention if the joints have been sealed before
Getting a quote
There’s no standard price list, because every job is different. Instead, we give you a clear price for your job. To arrange one, ring 0345 464 0079 or drop us an email.

Signs you need sand mastic in Puttenham
Some old mastic was never deep enough. A thin layer doesn’t hold well so we make sure the new mastic is the right thickness.
Common reasons people contact us are:
- Old sand mastic that has cracked, crumbled or fallen out
- Patchy fillers round a sash window
- Mastic worn away on windows facing the weather
- Mastic that needs renewing before redecorating
If you live in an older home near Church of St John the Baptist, the joint between an old wall and a newer frame is normally the first place rain gets in.
