- Working hours on commercial sites
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we’ll go through it with you.

A few details help us give you an accurate quote. When you get in contact, it helps to mention:

How we handle sand mastic in Monks Risborough
On many period windows, sand mastic looks right and suits the building. On modern frames we’d normally use a flexible sealant and we’ll explain which is best for yours. We work on timber door frames, tenement windows and brick reveals, and the jobs we see most are old sand mastic that has cracked, crumbled or fallen out and silicone on a period window that looks wrong.
Somewhere as small as Monks Risborough, older homes often have timber frames set in stone or brickwork. Older buildings like these don’t always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

Frames and glazing around Monks Risborough
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Rented homes near Monks Risborough station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about. Homes close to Church of St Dunstan include some older properties, and the joint between an old wall and a newer frame is usually the first place rain gets in.

Can I do it myself?
A DIY attempt does not rule out a professional job. We cut it out and start again.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
How it works
On the day, there’s very little for you to do. Show us the job and we will take it from there. The work itself takes a few hours for a single window, longer for several, including the tidy-up. In a small place like Monks Risborough, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each surround is checked first.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic is not too thick.
- New sand mastic is applied and shaped by hand.
- The finish is dressed neatly.

Where are you based?

What’s sand mastic made of?
It’s sand mixed with a linseed-oil-based binder for the joint between timber frames and masonry.
Is the work guaranteed?
Every job comes with our 12-month guarantee.
Can I choose the sealant colour?
Most of the time, yes. We’ll tell you which colours the right product comes in and agree one before we start.
Does someone need to be in?
It depends on the job. For work indoors, someone needs to let us in, and for outside work we’ll agree access with you when we book.
Do you take out the old sealant first?
Yes, every time. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
Surface by surface
Brick reveals
Sand mastic is also used where timber frames meet brick. It suits older brickwork.
Sash and case windows
The mastic round a sash window is on show so we finish it carefully.
Signs you need sand mastic in Monks Risborough
Shallow joints are a common cause. Mastic that is too thin cracks and drops out so we make sure the new mastic is the right thickness.
It’s worth asking for a quote if you see:
- Mastic round period door frames that has failed
- Cement or filler used on old window joints that has cracked
- Wind and rain getting in round a sash window
- Mastic worn away on windows facing the weather
Schools such as Princes Risborough Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.
What to look for in a quote
- How long the guarantee is
- How the joint is cleaned and prepared
- What insurance they hold
- Which sealant they’ll use, and why
What happens if it’s left?
Draughts round a sash window are not always the sashes. Gaps between the frame and the wall can be just as bad, and renewing the mastic closes them. In a small place like Monks Risborough, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
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, phone 0345 464 0079 or send us an email for an honest opinion and a quote.
