For landlords and businesses
Hotels need rooms back in use, so we plan the work room by room. We’ve worked in hotels as well as homes and businesses.
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.
Window mastic in Aston
Around Aston we seal all kinds of frames: from uPVC casements to timber and aluminium, along with patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. If you have draughty joints inside around the window and black, perished sealant on frames, we can help, whatever the surface.
Somewhere as small as Aston, older homes often have timber frames set in stone or brickwork. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
Each job carries a 12-month guarantee, whatever its size.

Why it’s worth doing now in Aston
Failed mastic is not a reason to replace sound windows. Where the frames are sound, new mastic normally deals with draughts and leaks at the edges. Problems with the glass or gaskets are for a window company, and we’ll say so. Around Aston, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
What it costs depends on the size of the job, how much old material has to come out and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.

DIY versus a professional finish
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
How the job changes by surface
Window sills
Every drop off the glass ends up on the sill, so the sill ends and the joint under the frame are vital. They’re cut out and resealed with exterior sealant.
Aluminium frames
Coated aluminium needs a compatible sealant and we avoid acetoxy silicones, which can react with some metals. We use a neutral-cure product.

What we do, step by step
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, do the work and tidy away. It generally takes a morning for a couple of windows and a door. Somewhere as small as Aston, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
Getting ready for the visit

Questions from Aston
Do you cover Aston for window mastic?
Yes. We work across London and the South East, and Aston is part of that. Just call 0345 464 0079 or email us with a few details of the job, and we will give you a clear price.
Do you work for landlords with property near Henley-On-Thames station?
Yes, we work for letting agents and landlords. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before we start.
Is it OK to seal over old sealant?
No, it won’t last. It may look fine at first, but the new layer lifts away from the old one. The old sealant has to come out completely.
Can you quote for more than one area?
Yes, we can. More than one area can go on one quote.
Can you get sealant to suit coloured frames?
Yes, we choose a colour to suit the frame. Anthracite grey, black, brown and white cover most frames, with clear as an option.
Do you have insurance?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Can new window sealant be painted?
Most silicone cannot be painted. If you plan to paint, tell us first and we can use a paintable sealant where it suits the joint.
What sealant do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Frames and glazing around Aston
With historic houses such as Greenlands (about 1 mile north-west) nearby, there’s older building stock in the area around Aston as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. 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.
If you live in an older home near Church of St Nicholas, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Rented homes near Henley-On-Thames station change hands often, and cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Clear any debris from frame drain holes
- Avoid blasting the frames with a pressure washer
- Repaint timber before it’s bare
- Paint up to the joint, not over it
Clean the frames with mild soapy water, and keep solvents and harsh chemicals off the joint.
A failed joint lets water into the wall a little at a time. Often the first sign is a damp patch inside or flaking paint on the reveal. Catching it early keeps the fix to a reseal.
