Lyford Window Mastic
Window and door frames in Lyford need attention? We cut out the old, prepare the joints and apply the right sealant, with a one-year guarantee.
- A bead that doesn’t match the frame
- Draughty joints inside around the window
- Old mastic that has gone black or come away
Do you need window mastic in Lyford?
Some failures date back to when the windows were fitted. Sealant run over dust, wet brick or loose mortar never bonded as it should, so it comes away long before its time.
If you can see any of these, it’s time to have the joints looked at:
- Cracked sealant at the sill ends
- Old mastic that has gone black or come away
- Cold air getting in at the frame edge
- Water coming in at the bottom corners of a door
For an older house near a landmark such as Church of St Mary, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Window mastic in Lyford
If you can feel air around a shut window, the gap is often at the frame. Resealing that joint can make a room feel noticeably less draughty and quietens the whistle on windy days. If the draught is through the window seals instead, we’ll tell you. If you have gaps between the frame and the inside reveal and gaps where the sill meets the wall, we can help, on timber windows & doors, patio & French doors and window sills alike.
Outdoor sealant needs dry, clean surfaces, so work on frames around Lyford is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
All our work is covered by a 12-month guarantee.

The process
We keep the work tidy and contained to the area we are working on, so you can get on with your day. Expect the work to take a few hours for a handful of frames, longer for a whole house, and we tell you how long to leave it before we go. Somewhere like Lyford needs a little journey planning: 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.
- First we look at every frame and agree the list.
- We remove the old mastic and clean the frame and the wall.
- Deep gaps are filled with backing rod to set the depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Finally we tidy up and check each joint.
How to prepare
- Keep pets and children clear of the area while we work
- Mention any leaks or damp you’ve noticed
- Tell us about access, such as stairs, a lift or high-level joints

Frames and glazing around Lyford
With historic houses such as Longworth House (about 3.2 miles north) nearby, there’s older building stock in the area around Lyford as well as newer homes. Where a home is older, 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.
In and around Lyford, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.

What affects the cost of window mastic
You’ll get a clear quote before work begins. It’s based on:
- How much old sealant there is and how hard it is to remove
- Whether there’s mould to deal with
- Access and height
- The product the joint needs
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 we start, so you know where you stand.
What we need to know
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- Photos by email, if that is easy
- Where the job is, and your postcode
- The type of property
- Access, such as stairs, a lift or height
Getting a quote is simple: let us know the job and the location and its rough size. A few pictures by email make the job easier to understand, and we’ll come back to you with a quote.
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.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
FAQs for Lyford
Is there a guarantee on window mastic in Lyford?
Every job comes with our one-year guarantee, wherever it is. We are fully insured, and an ARBOMaster approved applicator.
Do you cover smaller places like Lyford?
Yes, Lyford is covered. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Which products do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we will tell you what we’re using.
Do you work on first-floor windows?
Yes, where they can be reached safely. Tell us about access when you get in touch and we’ll plan for it.
Where do you work from?
Our base is in Crawley, and we cover South East England, London and all of Scotland.
Can you do the inside joint as well?
Yes. Outside is the weather seal; inside closes the gap to the plaster. We do one or both.
Will you leave a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
What should I tell you?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply call 0345 464 0079 or send us an email.
What the job involves on each surface
Aluminium frames
Aluminium needs a sealant that bonds to coated metal, and acetoxy silicones are not used, as they can attack some metals. We use a neutral-cure product.
Timber windows & doors
Timber moves with moisture as well as heat, so the joint must stay flexible. The paint or stain needs to be sound where the sealant meets it.
When it is not the sealant
It helps to know what we can’t do too:
- Condensation trapped between the panes
- Rotten timber, which needs a joiner first
- A sash or casement that won’t close properly
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we’ll tell you honestly.
