Window mastic for homes and businesses in The Common
Most frames have an outside joint and an inside one. The external joint is the weather seal; the internal joint closes the gap to the plaster and stops draughts. We seal one or both, depending on what’s needed. Common call-outs are for mastic that has split away from the wall and cracked internal joints between frame and plaster, on uPVC windows, composite doors and aluminium frames.
Mastic can only go onto a dry, clean joint, so window work in The Common is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
You’re covered for a year from the day we finish. If there’s a problem with it, please phone 0345 464 0079 or drop us an email.

Window mastic in The Common: local notes
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Managing a site like Radwinter Church of England Voluntary Aided Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages.
The Common is about 4 miles east of Saffron Walden, in Essex. Homes, rented property, offices and hotels in The Common is covered for window mastic, old or new, large or small.

How the visit works
The work is kept neat and contained to the area we’re working on, so you can get on with your day. Expect the work to take a few hours for a handful of frames, longer for a whole house. Somewhere as small as The Common, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by checking each window and door with you.
- 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.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Every joint is checked before we leave.
Getting ready for the visit
- Mention if the joints have been sealed before
- Tell us if parking is tricky
- Keep pets and children clear of the area while we work

Advice
Why deal with it now?
Running fresh sealant over the old joint is tempting, 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. Older cottages and farmhouses around The Common can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.
What you get with us
- Sanitary silicone with an anti-fungal additive in wet areas
- An ARBOMaster approved applicator
- Colour agreed with you before any work starts
- Arbo and Everbuild products

DIY sealant or a professional job?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Signs you need window mastic in The Common
Older frames were often sealed with products that set hard. Once it has hardened, the frame’s movement tears it from the wall, and a gap opens along one edge.
The problems people generally mention when they call are:
- White mastic on grey or black frames
- Cold air getting in at the frame edge
- Rain getting in at the frame or under the sill
- Untidy mastic left by window fitters
In the older streets around Church of St Mary the Virgin, the joint between an old wall and a newer frame is generally the first place rain gets in.

Work for landlords, hotels and businesses
We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we’ll quote.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
What the job involves on each surface
Patio & French doors
Not every patio door leak is a mastic problem: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We look for the cause first.
uPVC windows
The frame is cleaned with a product that won’t harm the plastic, then the new bead is laid against the frame and the wall.
The Common: your questions answered
Do you cover smaller places like The Common?
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.
What guarantee comes with window mastic in The Common?
All our work, in The Common and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.
Can you do several jobs on one visit?
Of course. Doing several areas at once is usually more efficient.
What do you need from me for a quote?
Only a few details: where it is, what you’ve noticed and how we reach it. Then ring 0345 464 0079 or drop us an email.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
What do you put in the joint?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Can you do the inside joint as well?
Yes. The outside joint keeps the weather out, and the inside joint stops draughts and finishes the reveal. We can do either or both.
Will you leave a mess?
Tidy work is part of the job. Nearby surfaces are protected.
What affects the cost of window mastic
We do not publish a price list, because jobs vary so much. What we look at:
- The number of rooms or windows
- Access and height
- The size of the job
- Working hours on commercial sites
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
What we need to know
When you call or email, it’s useful to know:
- What the problem is, such as mould, gaps, leaks or cracking
- If it’s domestic, commercial or a hotel
- Whether it has been sealed before
- The address or postcode of the job
There’s no standard price list, as no two jobs are quite the same. Instead, we give you a clear price for your job. To arrange one, call 0345 464 0079 or send us an email.
