What affects the quote in The Haven
Every job gets its own quote. These are the things that affect it:
- The size of the job
- The old material and how stubborn it is
- How many areas need sealing
- Working hours on commercial sites
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.
What to tell us for a quote
What to tell us when you ask for a quote:
- The type of property
- Any previous sealing or DIY work
- Any access issues, like height or stairs
- The address or postcode of the job
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and add photos by email if you can.

How it works
Most of a good job is in the preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes most of a day for a typical house, less for a few frames. Somewhere as small as The Haven, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check each frame and agree which ones need doing.
- We remove the old mastic and clean the frame and the wall.
- We fit backing rod in deep gaps so the sealant is the right depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- We clear up and check every joint is fully closed.
Preparing for the visit
- Mention if the joints have been sealed before
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about any water getting in

Advice
Should I try it myself first?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
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.
FAQs for The Haven
Do you cover The Haven for window mastic?
Yes. We work across London and the South East, and The Haven is part of that. You can ring 0345 464 0079 or drop us an email and let us know what needs doing.
Will you come out to The Haven?
Yes. The Haven is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
I rent my home. Can I book you?
We are happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.
How long does it take to reseal the windows on a house?
The work takes a few hours for a few frames, or a day or more for a whole house. Access and how stubborn the old mastic is affect the time most.
Can you get sealant to suit coloured frames?
Yes, we choose a colour to suit the frame. Anthracite grey, black, brown and white cover most frames, with clear as an option.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Do you seal inside as well as outside?
Yes. Outside is the weather seal; inside closes the gap to the plaster. We do one or both.
Do you work for landlords and businesses?
Yes, often. Several properties can be quoted together.
Signs you need window mastic in The Haven
Frames are never completely still. Sun on a frame makes it expand, and it contracts again overnight, while the brick or render around it hardly moves. A sealant that can’t keep up eventually tears.
Signs it’s time to call us include:
- Hard, cracked sealant around windows
- Draughty joints inside around the window
- Mastic that’s falling out in pieces
- Untidy mastic left by window fitters
Rented homes near Billingshurst station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Different surfaces, different methods
uPVC windows
Plastic frames move a lot between a hot afternoon and a cold night, so the joint needs a low-modulus sealant that stays flexible. We match white, brown, anthracite grey and black frames.
Patio & French doors
Patio and French doors have the longest joints on most houses. Most leaks start at the bottom corners, so we pay close attention there.
