About our sand mastic in Arundel
On many period windows, sand mastic looks right and suits the building. On modern frames we’d normally use a flexible sealant and we will explain which is best for yours. We work on timber door frames, brick reveals and tenement windows, and common reasons people get in touch are crumbling sand mastic round a window and wind and rain getting in round a sash window.
In smaller places like Arundel, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. Each frame material needs the right sealant against the right wall.
There’s a 12-month guarantee on every job, whatever its size.

What happens if it’s left?
Silicone might seem the quicker option, but it can look wrong on a period surround. Sand mastic suits the building and blends with the stone or brick. Homes in smaller places like Arundel can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we’ll explain what it covers.

Quotes for sand mastic in Arundel
For a quick quote, just ask. The main things that affect it are:

- Whether old sealant or filler has to be cut out

How it works
Most of a good job is in the preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours per window, depending on the condition of the joints. In a smaller place like Arundel, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- We start by checking each surround and agreeing the joints to renew.
- Old, loose mastic is raked out and the joint cleaned.
- 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
- Mention any sign-in or site rules at work premises
- Plan for the work area to be out of bounds to pets and children
- Where the joints are inside, avoid wetting them before we arrive
How to get a quote
Every job is quoted individually. Just call 0345 464 0079 or send us an email with the details.
Advice
What we’re called out for in Arundel
Sand mastic slowly weathers. It dries out, cracks and loses its grip on the stone or timber.
It’s worth asking for a quote if you see:
- Gaps between timber frames and stone or brick
- Failed mastic on an exposed elevation
- Mastic round period door frames that has failed
- Old cement repairs round a window that have failed
Letting a property close to Arundel station? Then any sash windows need sound mastic to keep draughts and rain out.
Comparing quotes
- How the surfaces are prepared before sealing
- Are they insured?
- How the colour is chosen
- When the joint can take water or movement
How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Go gently near the mastic when preparing windows
- Ask the planning authority about consent for listed or conservation-area homes
- Ask us before painting near the mastic
- Sort the mastic before the decorators arrive
Look at the mastic when you look over the windows. Catching cracks early keeps repairs small.
Once mastic starts to crumble, rain gets in. It can soak into the frame and the surrounding masonry, so renewing it early is worth it.
Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
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 fails, we can still redo it.

Frames and glazing around Arundel
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. With historic houses such as Ecclesden Manor (about 4.3 miles south-east) nearby, there’s older building stock in the area around Arundel as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
For site and facilities teams at buildings such as St Philip's Catholic Primary School, the mastic around its windows and doors needs looking after like any other building’s. Homes close to Trinity Congregational Church include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in.
