About our window mastic in Fenny Stratford
A window frame and the wall around it expand and shrink at different rates. Heat and cold make frames grow and shrink against brick or render that hardly moves. So the sealant has to stretch and recover, which is why we use a low-modulus product. We work on window sills, aluminium frames and uPVC windows, and common reasons people get in touch are gaps between the frame and the inside reveal and gaps left after new windows were fitted.
Houses in smaller places like Fenny Stratford can stand more in the open than those in a built-up town, so exposed windows and doors face the weather head on. The mastic around frames on those walls tends to age faster.
We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

Can I do it myself?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Questions from Fenny Stratford
Do you cover Fenny Stratford for window mastic?
Yes, Fenny Stratford is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or email us with a few details of the job, and we’ll send you a clear quote.
I let a flat near Fenny Stratford station. Can you help?
Yes. We work for landlords and agents as well as homeowners, and several properties can go on one quote. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll send you a clear quote.
Is it OK to seal over old sealant?
No, and we never do. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.
Do you do commercial work?
Yes. Larger jobs can be planned room by room or area by area to suit the site.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned.
Can new window sealant be painted?
That depends on the product. Silicone isn’t paintable, but some hybrid sealants are. Mention any painting plans before any work starts.
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.
Should I try DIY first?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
Signs you need window mastic in Fenny Stratford
A lot of older mastic was never designed to stay flexible. Once it’s rigid, every bit of frame movement pulls at it, leaving a hairline gap down one side.
Common reasons people contact us include:
- Sealant in the wrong colour for the frame
- Draughty joints inside around the window
- Gaps left after new windows were fitted
- Whistling draughts around closed windows
For an older house near a landmark such as Church of St Martin, the joint between an old wall and a newer frame is usually the first place rain gets in.

What affects the quote in Fenny Stratford
Jobs vary more than people expect. What affects the quote:
- Working hours on commercial sites
- Any mould that needs treating
- How easy the joints are to reach
- The amount of work
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
What to tell us for a quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- Whether it has been sealed before
- If it’s domestic, commercial or a hotel
- Photos by email, if that’s easy
- Where the property is
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will explain how we’d tackle it. When it suits you, call 0345 464 0079 or drop us an email.
Honest limits
To be straight with you, there are a few things sealant will not fix:
- Broken hinges, locks or handles
- Damp coming through the wall itself rather than the frame joint
- Soft or decayed wood in the frame
If in doubt, phone 0345 464 0079 or send us an email and we will say what we think before you book.

Why it’s worth doing now in Fenny Stratford
A cracked joint around a frame lets rain into the wall. Over time that can mean damp patches, damaged plaster and rotting timber. A reseal is a much smaller job. In an older home around Fenny Stratford, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.
We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.

Failed sealant is one of the commonest items on a check-out report. Several properties can be quoted together.
What happens on the day
At the end, we look at the finished work together and explain the cure time. The visit itself usually takes most of a day for a typical house, less for a few frames, depending on the size of the job. For a job in Fenny Stratford, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since 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.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- We tool each bead neatly and check every joint is closed.
How to prepare
- Clear the area around the work
- Keep pets and children clear of the area while we work
- Mention any parking rules near the property

Fenny Stratford homes and the weather
With historic houses such as Bletchley Park (about 1.1 miles west) nearby, there’s older building stock in the area around Fenny Stratford as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
