Window mastic in Roydon
From a single sill to a whole house of windows, the work is priced before anything is done. Just phone 0345 464 0079 or send us an email and tell us how many frames there are and how they’re reached. We work on patio & French doors, timber windows & doors and uPVC windows, and the jobs we see most are gaps left after new windows were fitted and black, perished sealant on frames.
Somewhere as small as Roydon, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
You’re covered for a year from the day we finish. If anything isn’t right with it, ring 0345 464 0079 or drop us an email.

Common problems we fix in Roydon
Some failures date back to when the windows were fitted. Mastic laid onto dusty, damp or crumbling surfaces never bonded as it should, so it comes away long before its time.
Any of these means the joints need attention:
- Cracked internal joints between frame and plaster
- Rain getting in at the frame or under the sill
- Old mastic that has gone black or come away
- A bead that doesn’t match the frame
In the older streets around St Peter's Church, the joint between an old wall and a newer frame is usually the first place rain gets in.
Questions to ask before you book
- Whether they seal over old material or remove it
- What happens if they find a problem under the old sealant
- What the cure time is
- What preparation is included
What affects the cost of window mastic
We don’t publish a price list, because no two jobs are the same. What we look at:
- The product the joint needs
- When we can work, for business premises
- How easy the joints are to reach
- How much old sealant there is and how hard it is to remove
The cost reflects the work involved, not guesswork. That’s why we ask about the job first and agree the price before starting.
Asking for a quote
When you call or email, it’s useful to know:
- Access, such as stairs, a lift or height
- Pictures of the joints, sent by email
- What the problem is, such as mould, gaps, leaks or cracking
- If it’s domestic, commercial or a hotel
Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we’ll talk you through what we’d do. When it suits you, ring 0345 464 0079 or email us.

Surface by surface
Patio & French doors
Door frames take knocks and movement every time the doors are used. The sealant must cope with it, where a rigid one would crack.
Composite doors
If the door itself is draughty, the issue may be the door seals or hinges rather than the frame mastic. We seal the frame and let you know about anything else.
Work for landlords, hotels and businesses
Landlords and agents in Roydon can book us as well as homeowners. Sealant work between tenants keeps a property looking cared for before the next move-in.
Mouldy or split sealant often shows up at the end of a tenancy. Several properties can go on one quote.
What we do, step by step
All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. It normally takes a few hours for a few frames, or a day or more for a whole house. In a small place like Roydon, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by checking each window and door with you.
- Next the failed sealant is cut away and the joint cleaned.
- Where gaps are deep, backing rod goes in first.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- We clear up and check every joint is fully closed.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- Keep children and pets away from the work area
- Try not to wet indoor joints just before the visit

Roydon questions
Can you help a landlord with a rental near Roydon station?
Yes, rental work is part of what we do. Just call 0345 464 0079 or send us an email and tell us about the property, and we will send you a clear quote.
Will you come out to Roydon?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Will there be a smell?
Sometimes, a little. It fades as the sealant cures.
Can you do the inside joint as well?
Yes. Draughts often come through the inside gap too, so sealing both is often worthwhile.
Is it OK to seal over old sealant?
No. The old sealant always comes out first, so the new sealant bonds properly.
Can you match the sealant to my frames?
Yes, we choose a colour to suit the frame. Grey and black frames get grey or black sealant, and wood-effect frames generally suit brown.
Which products do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice.
What does window mastic cost?
We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. You will get a clear quote before any work starts.
Roydon homes and the weather
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For landlords with property near Roydon station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. Managing a site like Roydon Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages.

Nearby you’ll also find Lowewood Museum (2.5 miles south-west) and Princess Alexandra Hospital (2 miles east). Open spaces near Roydon include Hunsdon Mead.
Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Keep timber frames painted
- Ventilate rooms so frames don’t stay wet inside
- Do not use solvent cleaners on the joint
- Check the mastic once a year
Timber frames need their paint kept up, since wood that gets wet swells and shrinks more. Keep paint off the silicone itself.
Leaks normally show up in wet, windy weather, but resealing works best in dry conditions. Sorting cracked mastic early means the joint is sound before the bad weather.
