Common questions in Loudwater
Is Loudwater in your area for window mastic?
Yes. Our work covers London and the South East, and Loudwater is part of that. You can call 0345 464 0079 or send us an email and let us know what needs doing.
Can you help a landlord with a rental near Bourne End station?
Yes, we work for landlords and agents. You can ring 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Do you seal inside as well as outside?
Yes. The outside joint keeps the weather out, and the inside joint stops draughts and finishes the reveal. We do one or both.
What information do you need?
The location, the problem and the rough size of the job. If you can, email a few pictures.
How much does window mastic cost in Loudwater?
Size, access and the old material all affect the cost. Call for a quick quote and we’ll talk you through it.
Do you work on first-floor windows?
Yes, in most cases. Access is planned before any work starts.
How long will my window job take?
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.
When is the sealant fully cured?
Different products cure at different speeds, so follow the cure time we give you when we finish.
Window mastic for homes and businesses in Loudwater
There are two joints on most windows. Outside, the mastic keeps rain out; inside, the joint between frame and plaster stops draughts and tidies the reveal. We seal one or both, depending on what’s needed. If you have rain getting in at the frame or under the sill and white mastic on grey or black frames, we can help, whatever the surface.
In smaller places like Loudwater, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. Each frame material needs the right sealant against the right wall.
You get a one-year guarantee, the same in Loudwater as everywhere else we work.

Quotes for window mastic in Loudwater
The price is agreed before any work begins. It’s based on:
- How many areas need sealing
- Any working-time requirements on site
- The type of sealant required
- Any mould that needs treating
What you pay reflects the work, not a rough estimate. That’s why we ask about the job first and send you a clear quote before any work starts.
Helping us quote
Photos help, but a description is a good start. Please mention:
- Any access issues, like height or stairs
- Pictures of the joints, sent by email
- What’s wrong with the joints now
- Whether it’s a home or a business
Call for a quick quote, or email us if that’s easier. Tell us about the joints that need doing and we will talk you through the work and give you a clear price.
Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Ventilate rooms so frames don’t stay wet inside
- Do not paint over the silicone
- Look round the frames every year or so
- Repaint timber before it’s bare
A yearly look round the frames is enough. Cracks and lifting edges are easy to spot early, and if anything looks wrong, just ring 0345 464 0079 or send us an email.
Water trapped behind a failed joint can start rot in timber frames and sills. Rotten timber needs a joiner, not a sealant, so it pays to reseal before that happens.
For landlords and businesses
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Loudwater homes and the weather
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. With historic houses such as Cliveden (about 3.5 miles south) nearby, there’s older building stock in the area around Loudwater as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
If you look after a building such as Loudwater Combined School, its window and door frames need their mastic kept sound, just like a home’s. For an older house near a landmark such as Church of St Peter, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Letting a property close to Bourne End station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Why act early in Loudwater
A cracked joint around a frame lets rain into the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. Resealing now is a small job by comparison. Homes in smaller places like Loudwater can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

What happens on the day
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The work itself takes a few hours for a few frames, or a day or more for a whole house. In a smaller place like Loudwater, 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 start by checking each window and door with you.
- Next the failed sealant is cut away and the joint cleaned.
- Deep gaps are filled with backing rod to set the depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Every joint is checked before we leave.
How to prepare
- Tell us about any previous sealing or DIY attempts
- On commercial sites, let us know about site rules
- Tell us if parking is tricky

What we cannot put right
Some problems need a builder, plumber or other trade rather than us:
- Soft or decayed wood in the frame
- A door that needs adjusting, rehanging or new seals
- Misting between the panes of a double-glazed unit (that needs a new unit)
Not sure which it is? You can call 0345 464 0079 or email us and we will tell you honestly.
What we seal
- Window sills
- Composite doors
- Patio & French doors
- uPVC windows
- Aluminium frames
- Timber windows & doors
Can I do it myself?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
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.
