How it works
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take most of a day for a typical house, less for a few frames. In a small place like Marlow Common, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check each frame and agree which ones need doing.
- The old mastic is cut out and the surfaces cleaned back.
- Where gaps are deep, backing rod goes in first.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Every joint is checked before we leave.
Before we arrive
- Mention any parking rules near the property
- Move anything stored near the joints
- Tell us about any water getting in

How we handle window mastic in Marlow Common
Homes in Marlow Common have every kind of window: from uPVC casements to timber and aluminium, plus patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. We work on window sills, timber windows & doors and aluminium frames, and common reasons people get in touch are cold air getting in at the frame edge and white mastic on grey or black frames.
Somewhere as small as Marlow Common, 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.
Big or small, it’s backed by our one-year guarantee.

DIY sealant or a professional job?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Why deal with it now?
Getting a straight, even bead on an outside frame takes practice, especially on upper floors. A professional job is cut out properly, backed where needed and finished neatly, in a sealant suited to the wall. Around Marlow Common, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re not sure whether it needs doing, call 0345 464 0079 or send us an email and we will give you an honest view and a quote.

Signs you need window mastic in Marlow Common
Plenty of failed mastic was poorly applied in the first place. Mastic laid onto dusty, damp or crumbling surfaces didn’t grip properly, and it lets go sooner than it should.
The most common problems we see are:
- A bead that doesn’t match the frame
- Gaps where the sill meets the wall
- Whistling draughts around closed windows
- Cracked internal joints between frame and plaster
For landlords with property near Marlow station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
What to look for in a quote
- When the joint can take water or movement
- Who does the work, and how experienced they are
- Whether all the old sealant comes out first
- How the surfaces are prepared before sealing
Aftercare tips
So the new joints stay in good condition:
- Don’t use solvent cleaners on the joint
- Walk round the house once a year and look at the joints
- Avoid blasting the frames with a pressure washer
- Wipe condensation off the frames
Check the drainage slots in the frames are not blocked, so water can run away instead of sitting against 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.
