FAQs for Redbridge
Do you work for landlords with property near Redbridge station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
Is window mastic in a coastal place like Redbridge any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Where is Mr Mastic based?
We work from Crawley. Our applicators cover Redbridge, along with the rest of our area.
Is the new sealant paintable?
Not if it’s silicone. Tell us your decorating plans and we will pick a sealant to suit.
How long should I leave it?
It depends on the product. We tell you how long to leave it before we go.
Do you do commercial work?
Yes. Hotels, offices and other businesses use us and we’re fully insured.
Do you hold any approvals?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.

How we handle window mastic in Redbridge
Homes in Redbridge have every kind of window: from uPVC casements to timber and aluminium, along with patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. We’re often asked to deal with damp patches on the reveal after heavy rain and whistling draughts around closed windows, across timber windows & doors, composite doors and window sills.
Outdoor sealant needs dry, clean surfaces, so work on frames around Redbridge is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
Our work is backed for twelve months, in Redbridge and everywhere else we cover.

Aftercare tips
Aftercare is simple:
- Keep solvents and bleach off the sealant
- Keep drainage slots and sill grooves clear
- Ventilate rooms so frames do not stay wet inside
- Keep jet washers away from the mastic
Timber frames need their paint kept up, because bare, wet timber moves more and pulls at the joint. Keep paint off the silicone itself.
Water trapped behind a failed joint can start rot in timber frames and sills. Rotten timber needs a joiner, not a sealant, so early resealing is worth it.
Landlords, agents and businesses in Redbridge
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
What affects the cost of window mastic
We don’t publish a price list, because no two jobs are the same. The quote depends on:
- The amount of work
- Mould in or behind the old joints
- Which sealant suits the joint
- Whether the work is at height
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, and we will explain the quote if you ask.
Asking for a quote
When you contact us, it’s useful to know:
- Where the job is, and your postcode
- A few pictures by email, if you can
- What the problem is, such as mould, gaps, leaks or cracking
- If it’s domestic, commercial or a hotel
Asking for a quote is easy: let us know what needs doing and where and its rough size. Photos by email help us understand the job, and we will take it from there.
How the visit works
There is not much for you to do on the day. Point us to the joints and we will get on with it. The work itself takes a morning for a couple of windows and a door from start to finish. Somewhere as small as Redbridge, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we look at every frame and agree the list.
- Next the failed sealant is cut away and the joint cleaned.
- Where gaps are deep, backing rod goes in first.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- Finally we tidy up and check each joint.
Preparing for the visit
- Mention any parking rules near the property
- Plan for the work area to be out of bounds to pets and children
- Tell us about access, such as stairs, a lift or high-level joints
How to get a quote
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email pictures if that is easy.
Advice
Windows and doors in Redbridge
Redbridge is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on the mastic around window and door frames, especially on the side facing the sea. With historic houses such as Southampton Tudor House and Garden (about 3.3 miles south-east) nearby, there’s older building stock in the area around Redbridge 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 live in an older home near All Saints, frames set in older brick or stone need a sealant that suits the wall as well as the frame. If you let a flat or house near Redbridge station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. If you look after a building such as Redbridge Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

Different surfaces, different methods
Composite doors
An exposed front door gets wind-driven rain, and the top and bottom corners tend to fail first. We pay most attention there.
uPVC windows
Some uPVC windows were sealed at fitting with a quick bead that never bonded. We cut it out, back any deep gaps and reseal properly.
What sealant work can’t fix
In fairness, some problems need a different trade:
- Penetrating damp from a failed cavity tray or render
- A failed sealed unit that has misted up
- Draughts through the window seals rather than the frame
Not sure which it is? You can call 0345 464 0079 or email us and we will tell you honestly before booking.

Why it’s worth doing now in Redbridge
Failed mastic is not a reason to replace sound windows. Where the frames are sound, new mastic usually deals with draughts and leaks at the edges. Problems with the glass or gaskets are for a window company, and we’ll say so. Around Redbridge, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Combining jobs into one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear quote for the lot.
