West Bergholt Window Mastic
Window mastic for West Bergholt, by sealant specialists with 20+ years’ experience. Rated 4.9 on Google from 180+ five-star reviews.

Common problems we fix in West Bergholt
Sills take more water than any other part of a window, so the sill ends and the joint below the frame are common leak points. Failed sealant there lets rain into the wall or behind the frame.
Common reasons people contact us are:
- Leaking joints at the ends of sills
- Whistling draughts around closed windows
- Cracked or shrunken mastic around the frame
- Damp patches on the reveal after heavy rain
Letting a property close to Colchester station? Then renewing tired window mastic between tenants heads off draught and damp complaints.

About our window mastic in West Bergholt
The mastic around a window or door seals the gap between the frame and the wall. Once that seal fails, wind and rain find the gap. Our applicators cut it out and replace it with a flexible, weatherproof sealant. If you’re dealing with mastic that’s falling out in pieces and rushed sealant from a window installation, we can help, whatever the surface.
Around West Bergholt, conservatories, garden rooms and patio doors are often part of the house. Those joints need the same attention as the main windows, and any older timber or sash windows need a sealant that suits them.
Big or small, you get the same one-year guarantee in West Bergholt and across Essex.

What else we do in West Bergholt
Leave it or put it right?
A quick bead over the top of old mastic looks like an easy fix, but new sealant can’t bond to old, crumbling mastic. It peels before long, and water still gets in behind. The old mastic has to come out. In a smaller place like West Bergholt, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
The cost depends on how much there is to do, how hard the old material is to remove and access to the work. We give a clear quote before work begins.
Why us?
- Neat joints and a tidy finish
- Trusted Arbo and Everbuild sealants
- We agree the colour with you first
- We’re fully insured

Can I do it myself?
If you’re set on DIY, put the effort into 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.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
Common questions in West Bergholt
Is West Bergholt in your area for window mastic?
Yes, West Bergholt is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job, and we’ll send you a clear quote.
I let a flat near Colchester station. Can you help?
Yes, we work for landlords and agents. You can phone 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before we start.
Will the old sealant be removed?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
Do you have sealant for grey or black windows?
Yes, we choose a colour to suit the frame. Grey and black frames get grey or black sealant, and wood-effect frames normally suit brown.
Can new window sealant be painted?
Silicone generally will not take paint. Let us know beforehand, and we will use a paintable product where it suits.
Can you reach windows above the ground floor?
Yes, where it’s safe. For high or awkward windows, we’ll tell you what access is needed.
Should I try DIY first?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
Do you do commercial work?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. Working times can be discussed when we quote.
How the visit works
You don’t need to clear the whole room or building before we come, only the area right around the joints. We protect the rest, and the work takes a few hours for a few frames, or a day or more for a whole house for a typical job. Parking around West Bergholt is generally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- We start by checking each window and door with you.
- We remove the old mastic and clean the frame and the wall.
- Where gaps are deep, backing rod goes in first.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Finally we tidy up and check each joint.
Getting ready for the visit
- Tell us about any water getting in

Advice
How the job changes by 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 acetoxy silicones are not used, as they can attack some metals. Neutral-cure sealant is the safe choice.
What affects the quote in West Bergholt
The quote reflects the job in front of us. We take into account:
- Whether the work is at height
- The old material and how stubborn it is
- The amount of work
- How many areas need sealing
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.
Asking for a quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- How many joints, rooms or windows are involved
- Photos by email, if that’s easy
- What the problem is, such as mould, gaps, leaks or cracking
- If it’s domestic, commercial or a hotel

What window mastic looks like in West Bergholt
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Schools such as St Helena School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. For an older house near a landmark such as St Mary the Virgin, the joint between an old wall and a newer frame is usually the first place rain gets in.

How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Wipe condensation off the frames
- Wash the frames with mild soapy water
- Check the mastic once a year
- Avoid harsh chemicals near the mastic
On timber frames, keep the paintwork in good order, because bare, wet timber moves more and pulls at the joint. Paint up to the joint, not over the silicone.
On timber windows, water behind the joint can lead to rot. Rotten timber needs a joiner, not a sealant, so early resealing is worth it.
