What affects the cost of window mastic
Every job gets its own quote. These are the things that affect it:
- How much there is to do
- Any working-time requirements on site
- Whether there’s mould to deal with
- The number of rooms or windows
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.
Asking for a quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- Any previous sealing or DIY work
- Whether it’s a home or a business
- Photos by email, if that is easy
- How many joints, rooms or windows are involved
Asking for a quote is easy: tell us what needs doing and where, and roughly how big it is. Photos by email help us understand the job, and we will come back to you with a quote.
Window mastic in Brook Street, done properly
Frames and walls don’t move together. 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. If you have whistling draughts around closed windows and mastic that’s falling out in pieces, we can put it right.
Homes in small places like Brook Street often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
You are covered for a year from the day we finish. If anything isn’t right with it, phone 0345 464 0079 or drop us an email.

Brook Street questions
Can you help a landlord with a rental near Brentwood station?
Yes. We work for landlords and agents as well as householders, and several properties can be quoted together. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear price.
Do you cover smaller places like Brook Street?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you seal inside as well as outside?
Yes. Plenty of draughts come through the inside joint as well as the outside, so sealing both is often worthwhile.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you do not need to watch us work.
What should I tell you?
Let us know what needs doing and where. We’ll ask anything else we need to know.
Do the sealants smell?
Possibly a little. Any smell clears as the sealant cures.
Can you seal over the old sealant?
No, because it fails. We remove every bit of old sealant first.
Is the work guaranteed?
Yes, for 12 months. Keeping drainage clear and checking the joints yearly helps them last.
Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Avoid harsh chemicals near the mastic
- Walk round the house once a year and look at the joints
- Don’t paint over the silicone
- Clear any debris from frame drain holes
Timber frames need their paint kept up, since wood that gets wet swells and shrinks more. Keep paint off the silicone itself.
A small gap around a frame only grows. As old mastic keeps shrinking, the gap widens, and heat escapes around the frame. A new joint closes it up.
Brook Street homes and the weather
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. With historic houses such as Hare Hall (about 3.2 miles south-west) nearby, there’s older building stock in the area around Brook Street as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you look after a building such as Holly Trees Primary School, its window and door frames need their mastic kept sound, just like a home’s. For an older house near a landmark such as Church of St Peter, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
Brook Street is about 2 miles south-west of Brentwood, in Essex. Homes, rented property, offices and hotels in Brook Street can book us for window mastic. Every job comes with our 12-month guarantee. Brook Street is one of 644 places in Essex we cover for window mastic. We also work in Chelmsford, about 13 miles from Brook Street.

Local landmarks in Brook Street
Around Brook Street, our work takes us to homes and buildings near Drapers' Academy, Weald Country Park and The Bull Inn and the streets around them. For rail, the closest station is Brentwood station, roughly 1.2 miles east of the centre. Nearby you will also find Upminster Tithe Barn Museum of Nostalgia (3.1 miles south) and Spire Hartswood Hospital (1.1 miles south-east). For a walk, there’s Warley Place.
Work for landlords, hotels and businesses
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
Hotels need rooms back in use, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
What we can’t put right
In fairness, there are a few things sealant will not fix:
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Draughts through the window seals rather than the frame
- Faulty window hardware
Not sure which it is? You can phone 0345 464 0079 or email us and we will tell you honestly.
Surfaces we seal
- Timber windows & doors
- Aluminium frames
- Window sills
- uPVC windows
- Patio & French doors
- Composite doors
How it works
We keep the work tidy and contained to the joints we’re treating, so you can get on with your day. Expect the work to take a morning for a couple of windows and a door, and we tell you how long to leave it before we go. Somewhere like Brook Street needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- Mention if the joints have been sealed before
- Mention any sign-in or site rules at work premises

Common problems we fix in Brook Street
Some failures date back to when the windows were fitted. Sealant run over dust, wet brick or loose mortar never bonded as it should, and it lets go sooner than it should.
If you can see any of these, it’s time to have the joints looked at:
- Old mastic that has gone black or come away
- Gaps where the sill meets the wall
- Cracked internal joints between frame and plaster
- Gaps left after new windows were fitted
For landlords with property near Brentwood station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

DIY versus a professional finish
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
