Upper Beeding Window Mastic
We cover Upper Beeding for mastic around window and door frames, sills and patio doors. Old sealant removed completely, joints prepared properly.
- Gaps where the sill meets the wall
- Water coming in at the bottom corners of a door
- Rushed sealant from a window installation
DIY versus a professional 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.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Window mastic in Upper Beeding, done properly
There are two joints on most windows. The external joint is the weather seal; inside, the joint between frame and plaster stops draughts and tidies the reveal. Either or both can be done. If you are dealing with white mastic on grey or black frames and rushed sealant from a window installation, we can help.
Outdoor sealant needs dry, clean surfaces, so work on frames around Upper Beeding is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
You are covered for a year from the day we finish. If anything is not right with it, call 0345 464 0079 or drop us an email.

Windows and doors in Upper Beeding
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 Portslade Manor (about 4.6 miles south-east) nearby, there’s older building stock in the area around Upper Beeding as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
Letting a property close to Shoreham-By-Sea station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. Homes close to The Parish Church of St Peter include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. If you look after a building such as Upper Beeding Primary School, its window and door frames need their mastic kept sound, just like a home’s.

Do you work for landlords with property near Shoreham-By-Sea station?

Is Upper Beeding in your area for window mastic?
Yes, Upper Beeding is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear quote.
Is it worth trying it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
What should I tell you?
Let us know what needs doing and where, with photos by email if possible. If we need more, we’ll ask.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Can I add another job to the visit?
Yes. Several rooms, windows or areas can go on one quote.
Can resealing stop a draught around my window?
In many cases. Air often gets in between the frame and the wall, and sealing the inside and outside joints closes that path.
Do you do commercial work?
Yes. Commercial and hotel work is a large part of what we do. Working times can be discussed when we quote.
How to look after the new joints
A little care helps the new joints last. We recommend:
- Walk round the house once a year and look at the joints
- Don’t paint over the silicone
- Wash the frames with mild soapy water
- Avoid harsh chemicals near the mastic
Clean the frames with mild soapy water, and keep solvents and harsh chemicals off the joint.
Signs to watch for: split or missing mastic, gaps, damp patches inside or black mould on the reveal. If you notice one, it’s time to get the joint looked at.

How it works
You don’t need to clear the whole room or building, only the area right around the joints. We protect the rest, and the work takes a morning for a couple of windows and a door for a typical job. In a small place like Upper Beeding, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely.
- The surfaces are cleaned and left dry.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Getting ready for the visit
- For business premises, tell us about site rules or sign-in
- Let us know if you’ve seen damp or leaks
- Clear items away from the joints we’re working on

Related advice
Why it’s worth doing now in Upper Beeding
If you are painting or rendering, reseal at the same time. Fresh joints finish the job neatly, and it’s easier while the walls are being worked on anyway. Where a wall is exposed, as many are in small places like Upper Beeding, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Doing several joints on one visit normally makes better use of the time than several visits. We will send you a clear quote for the lot.

What the job involves on each surface
Patio & French doors
Door frames take knocks and movement every time the doors are used. The sealant must cope with it.
Composite doors
Composite doors are normally hung in an uPVC-type frame, so its perimeter joint is sealed much like a window. We match the colour to the frame.
Landlord and commercial work in Upper Beeding
Letting agents often deal with us directly. Tell us the address, the job and how access works.
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 that we can handle for you.
