About our sand mastic in Turnfurlong
Across Turnfurlong, we renew sand mastic around sash and case windows. Each joint is raked out, prepared and pointed by hand, finished to suit the masonry. If you have cracked mastic round a front door frame and weathered mastic on the most exposed windows, we can help, on timber door frames, tenement windows and brick reveals alike.
Around Turnfurlong, conservatories, garden rooms and patio doors are often part of the house. Their glazing joints and frame seals are as much a part of the job as the windows, and any older timber or sash windows need a sealant that suits them.
Our work is backed for twelve months, in Turnfurlong and everywhere else we cover.

What we do, step by step
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours per window, depending on the condition of the joints, and the area is left clean. A visit to Turnfurlong is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We start by checking each surround and agreeing the joints to renew.
- Old, loose mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- We dress the surface so it sits neatly against the masonry.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- Tell us about access, such as stairs, a lift or high-level joints
- On commercial sites, let us know about site rules

How we quote for sand mastic
Call for a quick quote. The main things that affect it are:
- How many areas need sealing
- Whether the work is at height
- The old material and how stubborn it is
- Whether there’s mould to deal with
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we’ll go through it with you.
What to tell us for a quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- Where the job is, and your postcode
- A few photos by email, if you can
- How we’d reach the joints
- Any previous sealing or DIY work
Every job is quoted individually, so the first step is telling us about yours. Just call 0345 464 0079 or email us with the details.

What the job involves on each surface
Stone surrounds
We take care not to mark the stone while raking out the old mastic.
Tenement and terrace windows
Rows of sash windows on tenements and terraces often need renewing together. We can do one window or several.
Leave it or put it right?
Replacing sash windows is a big decision for a period home and on a listed home, consent may be needed. Where the frames are in good order, new mastic seals the surround. In a smaller place like Turnfurlong, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.

Windows and doors in Turnfurlong
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.
Rented homes near Aylesbury station change hands often, and any sash windows need sound mastic to keep draughts and rain out. If you look after a building such as Turnfurlong Junior School, its window and door frames need their mastic kept sound, just like a home’s. Homes close to Holy Trinity include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

FAQs for Turnfurlong

What sealant do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we’ll explain our choice.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
Do you do commercial work?
Yes. We have worked for hotels, offices and other businesses.
How long does sand mastic take to go off?
It forms a skin fairly soon, then hardens over a longer period. The weather and joint depth both affect it.
Can you quote for more than one area?
Yes. Just list everything you need and we’ll quote it together.
Can I paint the new mastic?
Sand mastic is normally left unpainted, as guidance on traditional windows advises. Ask us before decorating.
Should I try it myself first?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
