What affects the quote in Mid Lavant
For a quick quote, just ask. What matters most is:
- The number of rooms or windows
- Which sealant suits the joint
- Working hours on commercial sites
- The size of the job
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we will explain what it covers.
What we need to know
Photos help, but a description is a good start. Try to tell us:
- How many joints, rooms or windows are involved
- Any access issues, like height or stairs
- Where the job is, and your postcode

Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is, and we’ll explain how we’d tackle it. Whenever you’re ready, call 0345 464 0079 or drop us an email.
Window mastic in Mid Lavant: local notes
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. With historic houses such as Goodwood House (about 1.9 miles east) nearby, there’s older building stock in the area around Mid Lavant as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
If you look after a building such as Lavant CofE Primary School, its window and door frames need their mastic kept sound, just like a home’s. For landlords with property near Fishbourne station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. For an older house near a landmark such as Church of St Nicholas, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

FAQs for Mid Lavant
I let a flat near Fishbourne station. Can you help?
Yes. We work for letting agents and landlords as well as homeowners, and several properties can be quoted together. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
Will you come out to Mid Lavant?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Will resealing my frames help with draughts?
In many cases. The gap between frame and wall is a common source of draughts, and sealing the inside and outside joints closes that path.
How do I get a quote for window mastic in Mid Lavant?
Every job is different, so each one gets its own quote. For a quick quote, ring 0345 464 0079 or send us an email and tell us what needs doing and where.
Is it messy?
No. The area is protected while we work and cleaned up afterwards.
Do I have to be there?
It depends on the job. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
Do you have insurance?
Yes. We’re fully insured.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator.
DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
Landlords, agents and businesses in Mid Lavant
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
Looking after it afterwards
After the cure time, these simple habits help:
- Clean frames with a soft cloth and soapy water
- Do not paint over the silicone
- Ventilate rooms so frames do not stay wet inside
- Avoid harsh chemicals near the mastic
Try not to touch the new joint while it cures, following the cure time we give you. Keep jet washers away from the frames.
A small gap around a frame only grows. As the old mastic shrinks further, more air gets through, and heat escapes around the frame. A new joint closes it up.
How it works
We bring everything the job needs with us. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a morning for a couple of windows and a door. For a village or hamlet like Mid Lavant, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- 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 water getting in
- Tell us if parking is tricky
- Move anything stored near the joints

Advice
Different surfaces, different methods
Patio & French doors
Patio and French doors have the longest joints on most houses. The threshold and the bottom corners take the most water, so we pay close attention there.
Timber windows & doors
Where timber has rotted at the joint, it needs repairing first. We will point out any rot we find, as a joiner will need to deal with it.
