Window mastic in Arkley
Around Arkley we seal all kinds of frames: uPVC, aluminium, timber and composite, along with patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. We work on window sills, timber windows & doors and patio & French doors, and people most often call us about draughts coming in around windows and doors and sealant in the wrong colour for the frame.
From mansion-block windows to modern glazing in new flats, London has every kind of frame. Over the years, the sealant around them shrinks, cracks and pulls away, which is when draughts and damp patches appear in homes in Arkley.
There’s a 12-month guarantee on every job, large or small.

Frames and glazing around Arkley
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. Historic houses like Wyllyotts Manor (about 3.7 miles north-east) are a reminder that the area around Arkley has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
Arkley is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. If you look after a building such as Whitings Hill Primary School, its window and door frames need their mastic kept sound, just like a home’s.

What affects the cost of window mastic
Every job gets its own quote. These are the things that affect it:
- The number and length of the joints
- How many areas need sealing
- Working hours on commercial sites
- How easy the joints are to reach
Instead of a standard rate, 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.
Asking for a quote
To make quoting easier, let us know:
- Where the property is
- Roughly how big the job is
- The problem you’ve noticed
- Whether it’s a home or a business
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is. When it suits you, call 0345 464 0079 or email us.
Questions from Arkley
Can parking be tricky for a visit in Arkley?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.
Is Arkley in your area for window mastic?
Yes. We work across London and the South East, and Arkley is part of that. Just ring 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear quote.
Do the sealants smell?
Sometimes, a little. It fades as the sealant cures.
Will resealing my frames help with draughts?
It will if the frame joint is the problem. We find where the air is coming from before we reseal.
Can you quote for more than one area?
Yes. More than one area can go on one quote.
Is it messy?
Not at all. The area is protected while we work and cleaned up afterwards.
Should I try DIY first?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Is the new sealant paintable?
Not if it’s silicone. Tell us your decorating plans and we will pick a sealant to suit.
Landlords, agents and businesses in Arkley
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
Why act early in Arkley
Failed mastic is not a reason to replace sound windows. If the frames and glass are in good order, resealing the joints is often all that’s needed. Problems with the glass or gaskets are for a window company, and we’ll say so. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
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 play a part, and we will explain the quote if you ask.
Why book with us
- One-year guarantee on every job
- Full insurance on every job
- We leave the area clean and tidy
- Colour agreed with you before work begins

What we’re called out for in Arkley
Joints that are too thin or too deep fail early. A thin smear across a wide gap has nothing to it, and a gap filled solid cannot flex. Backing rod sets the right depth.
People normally contact us after spotting something like this:
- Draughty joints inside around the window
- Damp patches on the reveal after heavy rain
- Untidy mastic left by window fitters
- Black, perished sealant on frames
For landlords with property near Elstree & Borehamwood station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
Before you book anyone
- Whether the sealant suits the joint
- How hidden problems are handled
- Whether they seal over old material or remove it
- What the quote includes, VAT included or not
Honest limits
In fairness, there are a few things sealant will not fix:
- A failed sealed unit that has misted up
- Damp problems in the wall away from the window
- Soft or decayed wood in the frame
If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think before booking.
Where we work in Arkley

How the visit works
We bring everything the job needs with us, so you do not need to buy or prepare anything. Once we’ve agreed what’s being done, we protect the area and start. Most jobs take anything from an hour or two to a full day, depending on how many frames there are. In Arkley, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
Getting ready for the visit
- Let us know about stairs, lifts or work at height
- Try not to wet indoor joints just before the visit
- Tell us if parking is tricky

What else we do in Arkley
Surface by surface
Aluminium frames
Aluminium needs a sealant that bonds to coated metal and we avoid acetoxy silicones, which can react with some metals. We use a neutral-cure product.
Patio & French doors
Patio and French doors have the longest joints on most houses. Most leaks start at the bottom corners, so they get particular care.
