About our window mastic in Lower Shiplake
Over two decades of sealing frames has taught us which products suit which walls. We are ARBOMaster approved and fully insured, and every job is covered by a 12-month guarantee. Typical jobs include sealant in the wrong colour for the frame and gaps between the frame and the inside reveal, on patio & French doors, composite doors and timber windows & doors.
Somewhere as small as Lower Shiplake, older homes often have timber frames set in stone or brickwork. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.
Each job carries a 12-month guarantee.

What we do, step by step
Once we are on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes anything from an hour or two to a full day, depending on how many frames there are. Somewhere as small as Lower Shiplake, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
Preparing for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Let us know about earlier repairs to the joints
- Tell us if parking is tricky

What affects the cost of window mastic
For a quick quote, just ask. What matters most is:
- Whether old sealant or filler has to be cut out
- When we can work, for business premises
- How many areas need sealing
- How much there is to do

Asking for a quote
There’s no need for technical detail. Just tell us:
- Where the property is
- Whether it’s a home or a business
- Any previous sealing or DIY work
- How many joints, rooms or windows are involved
We quote each job on its own, so the first step is telling us about yours. Just phone 0345 464 0079 or drop us an email with the details, and pictures are welcome.
Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Keep timber frames painted
- Check the mastic once a year
- Wash the frames with mild soapy water
- Avoid blasting the frames with a pressure washer
Keep the new mastic undisturbed while it cures, following the cure time we give you. Keep jet washers away from the frames.
Wet, windy weather is when failed mastic shows itself, but sealant goes on best when frames and walls are dry. Sorting cracked mastic early means the joint is sound before the bad weather.
Window mastic in Lower Shiplake: local notes
With historic houses such as Greenlands (about 3.6 miles north) nearby, there’s older building stock in the area around Lower Shiplake as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. London and the South East are among the drier parts of the UK, 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 Shiplake Church of England School, the mastic around its windows and doors needs looking after like any other building’s.

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
Do you need window mastic in Lower Shiplake?
Every frame moves through the day. Sun on a frame makes it expand, and it contracts again overnight, while the masonry beside it stays put. If the sealant cannot stretch, it splits.
Most people get in touch after spotting one of these:
- Rain getting in at the frame or under the sill
- Untidy mastic left by window fitters
- Cracked sealant at the sill ends
- Cold air getting in at the frame edge
Homes close to Church of St Mary include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

DIY sealant or a professional job?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Leave it or put it right?
Failed mastic is not a reason to replace sound windows. If the frames and glass are in good order, resealing the joints is often all that is needed. Problems with the glass or gaskets are for a window company, and we’ll say so. Older cottages and farmhouses around Lower Shiplake can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
