About our window mastic in Turnfurlong
If you can feel air around a shut window, the gap is often at the frame. A new joint stops the air getting through. If the draught is through the window seals instead, we’ll tell you. We are often asked to deal with cold air getting in at the frame edge and black, perished sealant on frames, across uPVC windows, window sills and patio & French doors.
Houses in smaller places like Turnfurlong can stand more in the open than those in a built-up town, so exposed windows and doors face the weather head on. That is hard on the mastic around frames and sills.
We stand behind the work with a 12-month guarantee.

DIY sealant or a professional job?
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.
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.

What affects the quote in Turnfurlong
The price is agreed before any work begins. It’s based on:
- Access and height
- Mould in or behind the old joints
- The type of sealant required
- The number of rooms or windows
The cost depends on how much there is to do, how much old material has to come out and access to the work. You will have a clear quote before any work starts.
Asking for a quote
What to tell us when you ask for a quote:
- The rough size of the job
- Any previous sealing or DIY work
- The address or postcode of the job
- The problem you’ve noticed
For a quick quote, get us on the phone, or email us if that is easier. Tell us about the joints that need doing and we’ll talk you through the work before giving you a price.
Why act early in Turnfurlong
Working on frames from a ladder with a sealant gun isn’t easy, especially on upper floors. We cut out properly, back deep gaps and tool every joint neatly, in a sealant suited to the wall. In an older home around Turnfurlong, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we’ll explain what it covers.
Why Turnfurlong clients choose us
- More than 20 years in sealant work
- Tidy, careful work

Questions from Turnfurlong
Do you cover Turnfurlong for window mastic?
Yes, Turnfurlong is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or email us and let us know what needs doing.
Do you cover smaller places like Turnfurlong?
Yes, Turnfurlong is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Can you seal over the old sealant?
No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. It all has to come out first.
What do you need from me for a quote?
Let us know what needs doing and where, with photos by email if possible. If we need more, we will ask.
Will you leave a mess?
Tidy work is part of the job. Nearby surfaces are protected, and we clear up when we’re done.
Can you do the inside joint as well?
Yes. Draughts often come through the inside gap too, so it can be worth sealing both.
How long should I leave it?
That depends on the sealant used, so follow the cure time we give you.
Do you work for landlords and businesses?
Yes, regularly. We can quote for several properties at once, and between tenancies is a good time for the work.
When to call us in Turnfurlong
Joint shape matters as much as the product. A skim of sealant over a wide gap soon tears, while a joint packed solid can’t stretch. Backing rod sets the right depth.
Most people get in touch after spotting something like this:
- Cracked sealant at the sill ends
- Hard, cracked sealant around windows
- A bead that does not match the frame
- Gaps between the frame and the inside reveal
If you let a flat or house near Aylesbury station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

The process
When we arrive, we look over the joints with you first, so you know exactly what we’re doing. Surfaces next to the work are protected before we start. The work normally takes a few hours for a handful of frames, longer for a whole house. A visit to Turnfurlong is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
Preparing for the visit
- Mention any parking rules near the property
- Keep children and pets away from the work area
- For indoor joints, keep the area dry beforehand if you can

Advice
Aftercare tips
To keep the joints looking good and working properly:
- Keep timber frames painted
- Avoid blasting the frames with a pressure washer
- Look round the frames every year or so
- Clear any debris from frame drain holes
A yearly look round the frames is enough. Small splits are simple to catch before they leak.
On timber windows, water behind the joint can lead to rot. Rotten timber needs a joiner, not a sealant, so it pays to reseal before that happens.
Work for landlords, hotels and businesses
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements.
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
What window mastic looks like in Turnfurlong
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Managing a site like Turnfurlong Junior School? Then its window and door frames need their mastic kept sound, just like a home’s. In the older streets around Holy Trinity, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
