Window mastic in Bovingdon
Frames and walls don’t move together. Heat and cold make frames grow and shrink against brick or render that hardly moves. That’s why the joint needs a flexible, low-modulus sealant rather than something rigid. If you have cold air getting in at the frame edge and a bead that doesn’t match the frame, we can put it right.
Houses in smaller places like Bovingdon can stand more in the open than those in a built-up town. The mastic around frames on those walls tends to age faster.
The work is covered for a year after we finish. If anything is not right with it, phone 0345 464 0079 or send us an email.

What else we do in Bovingdon
DIY versus a professional finish
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Landlords, agents and businesses in Bovingdon
We also work for property managers and facilities teams. Several sites can be quoted together.
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
What affects the cost of window mastic
The price is agreed before any work begins. It takes into account:
- Working hours on commercial sites
- The size of the job
- The number of rooms or windows
- The old material and how stubborn it is
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. You will know the price before we begin.
What we need to know
There’s no need for technical detail. It helps if you can tell us:
- Whether it’s a home or a business
- If someone has resealed it before
- How we’d reach the joints
- A few photos by email, if you can

When it is not the sealant
We’ll always be straight with you, so here’s what sealant can’t fix:
- Faulty window hardware
- Penetrating damp from a failed cavity tray or render
- Misting between the panes of a double-glazed unit (that needs a new unit)
If you are not sure, just phone 0345 464 0079 or drop us an email and we’ll give you a straight answer before booking.
Surfaces we seal

Frames and glazing around Bovingdon
With historic houses such as Chenies Manor House (about 3.2 miles south) nearby, there’s older building stock in the area around Bovingdon as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For site and facilities teams at buildings such as Bovingdon Primary Academy, the mastic around its windows and doors needs looking after like any other building’s. For landlords with property near Hemel Hempstead station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. If you live in an older home near Church of St Lawrence, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

What happens on the day

We protect the rest, and the job takes a few hours for a few frames, or a day or more for a whole house for a typical job. Parking around Bovingdon is normally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- Deep gaps get closed-cell backing rod to set the depth.
- 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
- Tell us about any previous sealing or DIY attempts
- Mention any sign-in or site rules at work premises
- Where the joints are inside, avoid wetting them before we arrive

Related advice
How the job changes by surface
Patio & French doors
The joints around patio doors run a long way, top, sides and threshold. Most leaks start at the bottom corners, so we pay close attention there.
Window sills
The end joints of a sill tend to fail before the rest. A tight seal at each end keeps rain out of the wall.
Why act early in Bovingdon
Resealing frames is a short job: the visit takes anything from an hour or two to a full day, depending on how many frames there are. Leave it until water is coming in and you may need plastering and decorating as well. In an older home around Bovingdon, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.
