Littlefield Green: your questions answered
Do you work for landlords with property near Maidenhead station?
Yes, we work for landlords and letting agents. Just phone 0345 464 0079 or email us and tell us about the property, and we will send you a clear quote.
Is Littlefield Green within the area you cover?
Yes, we do. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you take out the old sealant first?
Yes, always, and completely. New sealant will not bond properly to old, so the joint is cleaned back first.
Do you do commercial work?
Yes. Larger jobs can be planned room by room or area by area to suit the site.
Can new window sealant be painted?
It depends on the sealant. Silicone is not paintable, but some hybrid sealants are. Tell us if you’re decorating and we’ll choose accordingly.
Can you seal the gap between the frame and the plaster indoors?
Yes. Plenty of draughts come through the inside joint as well as the outside, so sealing both is often worthwhile.
Can I add another job to the visit?
Yes, we can. More than one area can go on one quote.
Can you seal over the old sealant?
No. We remove every bit of old sealant first.
About our window mastic in Littlefield Green
The mastic around a window or door seals the gap between the frame and the wall. When it cracks, hardens or pulls away, draughts and rain get in. The old mastic is removed and the joint resealed with a flexible exterior sealant. We are often asked to deal with cold air getting in at the frame edge and untidy mastic left by window fitters, across aluminium frames, patio & French doors and composite doors.
Somewhere as small as Littlefield Green, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
Our work is backed for twelve months, in Littlefield Green and everywhere else we cover.

Leave it or put it right?
A cracked joint around a frame lets rain into the wall. Over time that can mean damp patches, damaged plaster and rotting timber. Resealing now is a small job by comparison. Older cottages and farmhouses around Littlefield Green can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we will go through it with you.

What the job involves on each surface
Window sills
The end joints of a sill tend to fail before the rest. We reseal them so rain cannot run into the wall.
Composite doors
Composite doors are normally hung in an uPVC-type frame, and the joint around it is sealed like a window. The bead is colour-matched to the frame.
Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

Frames and glazing around Littlefield Green
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Dorney Court (about 4.3 miles north-east) are a reminder that the area around Littlefield Green has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Homes close to Church of St Mary include some older properties, and the joint between an old wall and a newer frame is usually the first place rain gets in. For landlords with property near Maidenhead station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. Managing a site like Holyport College? Then the mastic around its windows and doors needs looking after like any other building’s.

What to tell us for a quote
Photos help, but a description is a good start. Try to tell us:
- How many joints, rooms or windows are involved
- The problem you’ve noticed
- The type of property

How to look after the new joints
No joint lasts for ever, but care makes a real difference. A few tips:
- Keep paint and stain on wooden frames in good order
- Don’t use solvent cleaners on the joint
- Air rooms to keep condensation down around windows
- 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 sealant goes on best when frames and walls are dry. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
When it is not the sealant
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- A sash or casement that will not close properly
- A frame that has rotted at the joint
- Misting between the panes of a double-glazed unit (that needs a new unit)
If you are not sure, just ring 0345 464 0079 or send us an email and we will give you a straight answer before you book.
