Window & door mastic in Chorleywood West, Hertfordshire
Professional window mastic in and around Chorleywood West, with old sealant always removed completely.
- Gaps where the sill meets the wall
- Draughty joints inside around the window
- Sealant in the wrong colour for the frame
Common problems we fix in Chorleywood West
Plenty of failed mastic was poorly applied in the first place. Mastic laid onto dusty, damp or crumbling surfaces never bonded as it should, so it comes away long before its time.
Most people get in touch after spotting one of these:
- Rushed sealant from a window installation
- Gaps between the frame and the inside reveal
- Cracked or shrunken mastic around the frame
- Mastic that is falling out in pieces
Schools such as Arnett Hills Junior Mixed and Infant School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

Window mastic in Chorleywood West, done properly
Around Chorleywood West we seal all kinds of frames: uPVC, aluminium, timber and composite, plus patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. We are often asked to deal with hard, cracked sealant around windows and mastic that’s falling out in pieces, across aluminium frames, uPVC windows and window sills.
Mastic can only go onto a dry, clean joint, so window work in Chorleywood West is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
All of our work is guaranteed for twelve months.

Questions from Chorleywood West

Do you cover Chorleywood West for window mastic?
Yes, Chorleywood West is within the area we cover. Our work covers London and the South East. Just ring 0345 464 0079 or email us with a few details of the job.
What information do you need?
Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply call 0345 464 0079 or send us an email.
Can I do it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Will new mastic stop draughts?
Often, yes. Air often gets in between the frame and the wall, and sealing the inside and outside joints closes that path.
Can you quote for more than one area?
Yes. Several rooms, windows or areas can go on one quote.
Do you hold any approvals?
Yes. We are an ARBOMaster approved applicator, which is run for the Arbo sealant brand.

We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.

- The number and length of the joints
- Which sealant suits the joint
- How much old sealant there is and how hard it is to remove
- Whether there’s mould to deal with
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are unsure, ring 0345 464 0079 or send us an email for an honest opinion and a quote.

How the visit works
You do not need to clear the whole room or building, just the space around the work. We protect the rest, and the work takes a morning for a couple of windows and a door for a typical job. For a village or hamlet like Chorleywood West, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We check how each frame can be reached safely.
- All the failed sealant is cut away.
- 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.
- We tool the joint so water runs off, then clear up.
Preparing for the visit
- Move anything stored near the joints
- Mention any sign-in or site rules at work premises
- Let us know about parking restrictions

Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Do not paint over the silicone
- Check the mastic once a year
- Don’t aim a pressure washer at the joints
- Avoid harsh chemicals near the mastic
On timber frames, keep the paintwork in good order, because bare, wet timber moves more and pulls at the joint. Paint up to the joint, not over the silicone.
Water gets in quietly when mastic fails. Often the first sign is a damp patch inside or flaking paint on the reveal. Catching it early keeps the fix to a reseal.
Chorleywood West homes and the weather
Historic houses like Chenies Manor House (about 2.8 miles north-west) are a reminder that the area around Chorleywood West 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. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For landlords with property near Rickmansworth station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. For an older house near a landmark such as Church of St Peter, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

What the job involves on each surface
Window sills
Masonry sills can have joints where water gets in, and the joint under the frame can let rain run behind. Those are sealed with a product suited to stone or concrete.
Aluminium frames
Large aluminium doors have long joints down each side and across the head, and the bottom joint sees the most water. Each is cleaned, backed where deep and resealed.
Work for landlords, hotels and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can be quoted together.
