Window mastic for homes and businesses in Marlow Bottom
Most frames have an outside joint and an inside one. 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. We work on window sills, timber windows & doors and composite doors, and the jobs we see most are mastic that’s falling out in pieces and white mastic on grey or black frames.
Around Marlow Bottom, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
We stand behind the work with a 12-month guarantee, so you’re covered after we’ve gone.

Frames and glazing around Marlow Bottom
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Harleyford Manor (about 2.8 miles south-west) are a reminder that the area around Marlow Bottom has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
If you live in an older home near St Mary the Virgin, the joint between an old wall and a newer frame is usually the first place rain gets in. If you look after a building such as Burford School, its window and door frames need their mastic kept sound, just like a home’s.

What the job involves on each surface
Timber windows & doors
On period timber windows, traditional sand mastic is sometimes the better choice. We’ll tell you which suits your home.
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.
DIY versus a professional finish
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.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
How the visit works
The work is kept neat and contained to the area we are working on. The job normally takes a few hours for a few frames, or a day or more for a whole house, and we explain the cure time before we leave. Somewhere as small as Marlow Bottom, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- Mention any leaks or damp you’ve noticed
- Tell us about access, such as stairs, a lift or high-level joints

Where is Mr Mastic based?

Is it OK to seal over old sealant?
No, because it fails. The old sealant always comes out first, so the new sealant bonds properly.

Should I try DIY first?

Do you work on first-floor windows?
Yes, where they can be reached safely. Let us know about access when you ask for a quote and we’ll plan for it.
When it is not the sealant
Sealant is not the answer to every problem, and we’ll tell you before we start. Sealant won’t put right:
- Worn gaskets, brush seals or a door that has dropped
- A frame that has rotted at the joint
- Broken hinges, locks or handles
Not sure which it is? You can call 0345 464 0079 or drop us an email and we’ll tell you honestly before you book.

Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Do not use solvent cleaners on the joint
- Paint up to the joint, not over it
- Wipe condensation off the frames
- Use gentle cleaners on frames and sealant
Wipe the frames with soapy water when you clean the windows, and keep solvents and harsh chemicals off the joint.
Wet, windy weather is when failed mastic shows itself, but resealing works best in dry conditions. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.

Leave it or put it right?
Failed mastic is not a reason to replace sound windows. Where the frames are sound, new mastic usually deals with draughts and leaks at the edges. If we find failed glass units or worn seals, we will tell you. Around Marlow Bottom, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Ask us for a quote and we will go through it with you.

What we’re called out for in Marlow Bottom
Sun, frost and rain wear sealant out. Sunlight dries the surface out, and over the years it loses its give, cracks and comes away.
Signs it’s time to call us include:
- Mastic that has split away from the wall
- Gaps between the frame and the inside reveal
- Rain getting in at the frame or under the sill
- Untidy mastic left by window fitters
Letting a property close to Marlow station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
