Window mastic in Wash Common, done properly
If you can feel air around a shut window, the gap is often at the frame. Resealing that joint can make a room feel noticeably less draughty and quietens the whistle on windy days. If the draught is through the window seals instead, we will tell you. If you have gaps left after new windows were fitted and cracked sealant at the sill ends, we can put it right, on patio & French doors, timber windows & doors and composite doors alike.
Many houses in smaller places like Wash Common have conservatories, garden rooms or patio doors. Those joints need the same attention as the main windows, and any older timber or sash windows need a sealant that suits them.
Every job is covered by a 12-month guarantee.

What the job involves on each surface
uPVC windows
Fitters’ mastic on plastic frames is sometimes thin and rushed. It comes out, deep gaps get backing rod and the joint is resealed.
Timber windows & doors
Wood swells when it’s wet and shrinks when it dries, so a flexible sealant is essential. We seal onto sound, dry paintwork or timber.
Window mastic in Wash Common: local notes
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Benham Park (about 2.4 miles north-west) nearby, there’s older building stock in the area around Wash Common as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Rented homes near Newbury station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints. Homes close to St Luke Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Keep drainage slots and sill grooves clear
- Clean frames with a soft cloth and soapy water
- Keep paint and stain on wooden frames in good order
- Paint up to the joint, not over it
Have a look at the joints once a year, ideally after winter. Cracks and lifting edges are easy to spot early.
Look out for the warning signs: split or missing mastic, gaps, damp patches inside or black mould on the reveal. Any of these is worth a call.

What happens on the day
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for a handful of frames, longer for a whole house, and the area is left clean. For a job in Wash Common, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely.
- Frame and wall are cleaned and must be dry before sealing.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.
How to prepare
- Try not to wet indoor joints just before the visit
- On commercial sites, let us know about site rules
- Mention if the joints have been sealed before

Advice
Why deal with it now?
Draughts and leaks don’t always mean new windows. Where the frames are sound, new mastic normally deals with draughts and leaks at the edges. If we find failed glass units or worn seals, we will tell you. Homes in smaller places like Wash Common 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.
Every job is a little different, so we quote each one individually. 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.

When to call us in Wash Common
Sills take more water than any other part of a window, so the sill ends and the joint below the frame are common leak points. Failed sealant there lets rain into the wall or behind the frame.
Look out for these signs:
- Black, perished sealant on frames
- Mastic that has split away from the wall
- Untidy mastic left by window fitters
- Sealant in the wrong colour for the frame
Managing a site like Falkland Primary School? Then the mastic around its windows and doors needs looking after like any other building’s.
Questions to ask before booking
- The length of the guarantee
- Which colour the sealant will be
- How long to leave it before use
- What insurance they hold
