Window mastic in Bushey Heath
A cold draught around a closed window often comes from the frame edge. A new joint stops the air getting through and quietens the whistle on windy days. Where the air is getting in through the window itself, we’ll say so. We work on patio & French doors, window sills and timber windows & doors, and common reasons people get in touch are a bead that doesn’t match the frame and mastic that has split away from the wall.
Around Bushey Heath, conservatories, garden rooms and patio doors are often part of the house. Their glazing joints and frame seals are as much a part of the job as the windows.
Whatever the size of the job, it’s backed by our 12-month guarantee.

What else we do in Bushey Heath
What we do, step by step
All our tools and materials come with us in the van, so you do not need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. It normally takes a morning for a couple of windows and a door. In a smaller place like Bushey Heath, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- We check each frame and agree which ones need doing.
- The old mastic is cut out and the surfaces cleaned back.
- Where gaps are deep, backing rod goes in first.
- 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
- Tell us if parking is tricky
- Tell us about any water getting in
- Try not to wet indoor joints just before the visit

Do you need window mastic in Bushey Heath?

Bushey Heath homes and the weather
With historic houses such as Headstone Manor (about 2.8 miles south) nearby, there’s older building stock in the area around Bushey Heath as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. 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.
Schools such as Bushey Heath Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. Letting a property close to Carpenders Park station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Common questions in Bushey Heath
Is Bushey Heath within the area you cover?
Yes, Bushey Heath is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can you do window mastic in Bushey Heath?
Yes. We work across London and the South East, and Bushey Heath is part of that. Just call 0345 464 0079 or send us an email with a few details of the job.
How long does it take to reseal the windows on a house?
The work takes anything from an hour or two to a full day, depending on how many frames there are. Access and the amount of old mastic make the biggest difference.
Does someone need to be in?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
Are you insured?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
What does window mastic cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we will talk you through it.
Is the new sealant paintable?
Silicone generally won’t take paint. Let us know beforehand, and we will use a paintable product where it suits.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned before resealing.
Why deal with it now?
Draughts and leaks do not always mean new windows. Where the frames are sound, new mastic generally deals with draughts and leaks at the edges. If we find failed glass units or worn seals, we will tell you. Around Bushey Heath, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
What it costs depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before work begins, so you know where you stand.

- A 12-month guarantee on all work
