Window mastic for homes and businesses in Cyprus
Mr Mastic’s applicators have more than 20 years’ experience with window and door sealants. We’re ARBOMaster approved and fully insured, and every job is covered by a 12-month guarantee. Typical jobs include rain getting in at the frame or under the sill and leaking joints at the ends of sills, on timber windows & doors, window sills and patio & French doors.
Much of London’s older housing was built with timber sash windows, some still in place and some long since replaced. Whatever is in the opening now, the joint between frame and wall is what keeps the weather out, in Cyprus as anywhere.
Big or small, it’s backed by our one-year guarantee in Cyprus and across Greater London.

Windows and doors in Cyprus
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Eastbury Manor House (about 2.3 miles north-east) are a reminder that the area around Cyprus has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
For landlords with property near Woolwich station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. Managing a site like Winsor Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages.
Cyprus is about 2 miles east of Canning Town, in Greater London. Wherever you are in the E6 postcode area, we cover window mastic for homes and businesses. Our area takes in 764 places across Greater London. There’s also a page for London, about 7 miles away.
Every address in E6 and E16 is within our area for window mastic. We cover properties on Strait Road, Harper Road and Trader Road and the roads around them. Other places close to Cyprus include Beckton (1 mile north-east), North Woolwich (1 mile south), Royal Docks (1 mile west), East Ham (1 mile north) and Custom House (1 mile west). Further out, we also cover London (7 miles west), City of Westminster (9 miles west), Marylebone (9 miles west), Kensington (11 miles west), St Pancras (8 miles west) and Shoreditch (6 miles west).
Around Cyprus
We work in homes and buildings around Oasis Academy Silvertown, London Design and Engineering UTC and Beckton District Park and the streets around them. For rail, the closest station is Woolwich station, about 1.3 miles south. Nearby you will also find Greenwich Castle (3.6 miles south-west) and Albert Dock Seamen's Hospital (1.1 miles west). Open spaces near Cyprus include Gilbert's Pit.
What happens on the day
We keep the work tidy and contained to the joints we are treating, so you can get on with your day. Expect the work to take most of a day for a typical house, less for a few frames. For a job in Cyprus, parking and access are the things to plan: let us know about parking, the floor we’ll be working on and any lift or shared entrance.
- First we look at every frame and agree the list.
- Next the failed sealant is cut away and the joint cleaned.
- 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.
- Finally we tidy up and check each joint.
Preparing for the visit
- Move anything stored near the joints
- Let us know if you’ve seen damp or leaks
- Tell us if parking is tricky
How to get a quote
Every job is quoted individually, so the first step is telling us about yours. Just ring 0345 464 0079 or send us an email with the details and send pictures if you have them.
Related advice
When to call us in Cyprus
Water runs down the glass onto the sill, so the sill ends and the joint below the frame are common leak points. Failed sealant there lets rain into the wall or behind the frame.
The most common problems we see are:
- Gaps between the frame and the inside reveal
- Rain getting in at the frame or under the sill
- Hard, cracked sealant around windows
- Gaps where the sill meets the wall
As a London address, Cyprus can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.
Questions to ask before you book
- Is VAT in the price?
- How the surfaces are prepared before sealing
- Whether you can choose the colour
- How long to leave it before use
How we quote for window mastic
There’s no set price list, because no two jobs are the same. The quote depends on:
- How many areas need sealing
- Whether old sealant or filler has to be cut out
- Access and height
- The product the joint needs
What you pay reflects the work, not guesswork. That is why we ask a few questions first and agree the price before starting.
Asking for a quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- What’s wrong with the joints now
- The rough size of the job
- Access, such as stairs, a lift or height
- The address or postcode of the job

What the job involves on each surface
Window sills
Masonry sills can have joints where water gets in, including the one between the sill and the frame above. Those are sealed with a product suited to stone or concrete.
Timber windows & doors
Where timber has rotted at the joint, it needs repairing first. If we find rot, we will tell you before going ahead, as a joiner will need to deal with it.
Why it’s worth doing now in Cyprus
A cracked joint around a frame lets rain into the wall. Over time that can mean damp patches, damaged plaster and rotting timber. Resealing now is a small job by comparison. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Cyprus, the repair is bigger than a sealant job.
Doing several joints on one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

DIY versus a professional finish
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Cyprus questions
Is parking an issue for window mastic in Cyprus?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.
Can you help a landlord with a rental near Woolwich station?
Yes, we work for letting agents and landlords. You can phone 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before work begins.
Do you guarantee window mastic?
Yes, for 12 months. A yearly look at the joints helps them last.
Will resealing my frames help with draughts?
Yes, if the air is getting in around the frame. If it’s through the window’s own seals or a hinge, that’s a different fix, and we will say so.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
Is it messy?
Very little: the area around the joints is protected first, and we tidy up before we go.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We’ll tell you what we are using and why.
How long should I leave it?
That depends on the sealant used, so follow the cure time we give you.
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Check the mastic once a year
- Air rooms to keep condensation down around windows
- Clear any debris from frame drain holes
- Avoid blasting the frames with a pressure washer
Silicone can’t usually be painted, so if you are planning to paint the frames or walls, tell us beforehand. We can use a paintable sealant where that matters.
On timber windows, water behind the joint can lead to rot. Once wood has rotted, it needs repair before it can be sealed, so early resealing is worth it.
