Window & door mastic in Hungerford, West Berkshire
We cover Hungerford for mastic around window and door frames, sills and patio doors. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.
- Rushed sealant from a window installation
- Cracked internal joints between frame and plaster
- White mastic on grey or black frames
How we handle window mastic in Hungerford
Behind a thin line of old mastic there’s sometimes a deep void. Packing it solid with sealant gives a joint that can’t flex, so we fit backing rod to set the right depth. That way the new bead bonds to the frame and the wall only. If you are dealing with cold air getting in at the frame edge and rushed sealant from a window installation, we can put it right, whatever the surface.
Around Hungerford, conservatories, garden rooms and patio doors are often part of the house. Those joints need the same attention as the main windows.
A one-year guarantee comes as standard, so you’re covered after we have gone.

Common questions in Hungerford
Is Hungerford within the area you cover?
Yes. Hungerford is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you cover Hungerford for window mastic?
Yes. Our work covers London and the South East, and Hungerford is part of that. Just call 0345 464 0079 or send us an email with a few details of the job, and we’ll send you a clear quote.
Can you seal over the old sealant?
No. New silicone won’t bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Do you take out the old sealant first?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Will resealing my frames help with draughts?
Yes, if the air is getting in around the frame. If it’s coming through the window seals, we will tell you.
How many windows can you do in a day?
Allow a few hours for a handful of frames, longer for a whole house. Access and the amount of old mastic make the biggest difference.
Can new window sealant be painted?
Most silicone cannot be painted. Let us know beforehand, and we’ll use a paintable product where it suits.
Do you hold any approvals?
Yes. We’re approved under the ARBOMaster scheme, the approved applicator scheme for Arbo sealants.

Should I try it myself first?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
What happens on the day
When we arrive, we look over the joints with you first. Surfaces next to the work are protected before any work begins. The work usually takes a morning for a couple of windows and a door. A visit to Hungerford is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We start by checking each window and door with you.
- The old mastic is cut out and the surfaces cleaned back.
- Deep gaps are filled with backing rod to set the depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- We clear up and check every joint is fully closed.
Preparing for the visit
- Clear the area around the work
- Tell us if parking is tricky
- Where the joints are inside, avoid wetting them before we arrive
Ask for a quote
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email pictures if that’s easy.
Advice
Looking after it afterwards
To keep the joints looking good and working properly:
- Clear any debris from frame drain holes
- Use gentle cleaners on frames and sealant
- Do not paint over the silicone
- Keep paint and stain on wooden frames in good order
On timber frames, keep the paintwork in good order, because bare, wet timber moves more and pulls at the joint. Keep paint off the silicone itself.
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.
What affects the cost of window mastic
The price is agreed before any work begins. It takes into account:
- Access and height
- How much old sealant there is and how hard it is to remove
- Working hours on commercial sites
- How many areas need sealing
Combining jobs into one visit is generally more efficient than separate visits. We’ll give you a clear price for the lot.
Asking for a quote
To make quoting easier, please include:
- If it’s domestic, commercial or a hotel
- What the problem is, such as mould, gaps, leaks or cracking
- Pictures of the joints, sent by email
- Whether it has been sealed before
There’s no standard price list. Instead, we send you a clear quote for your job. To arrange one, call 0345 464 0079 or email us.
Why deal with it now?
Not every sealant suits a window. Decorators’ caulk and bathroom silicone are not designed for outside joints that move. An exterior, low-modulus sealant stays flexible in sun and frost. In an older home around Hungerford, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

Signs you need window mastic in Hungerford
Mastic ages in the weather. Sunlight dries the surface out, and over the years it loses its give, cracks and comes away.
Signs it’s time to call us include:
- Mastic that has split away from the wall
- Whistling draughts around closed windows
- Cracked internal joints between frame and plaster
- Rain getting in at the frame or under the sill
Schools such as Hungerford Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.
Questions to ask before booking
- Whether they seal over old material or remove it
- How the joint is cleaned and prepared
- Who turns up on the day
- Is VAT in the price?
