Great Linford: your questions answered
I let a flat near Wolverton station. Can you help?
Yes. We work for landlords and agents as well as householders. You can call 0345 464 0079 or email us with the details for a clear quote.
Do you cover Great Linford for sand mastic?
Yes, Great Linford is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or send us an email and let us know what needs doing, and we’ll give you a clear price.
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. We remove it all first.
What information do you need?
Let us know what needs doing and where. If we need more, we will ask.
Is consent needed for window work on a listed home?
Check with your local planning authority. They’ll tell you if consent is needed.
Do you offer different sealant colours?
We help you choose a colour that suits. The choice depends on the product the joint needs.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Are you fully insured?
Yes. We are fully insured.
How we handle sand mastic in Great Linford
Sand mastic skins over fairly quickly but full hardening takes longer. Traditionally, sand mastic is left unpainted, so ask us before you decorate. We work on stone surrounds, tenement windows and brick reveals, and the jobs we see most are a silicone bead on a sash window that spoils the look and cracked mastic round a front door frame.
In a smaller place like Great Linford, some walls face open ground and catch the full force of the weather. The mastic around frames on those walls tends to age faster.
Big or small, you get the same 12-month guarantee.

DIY versus a professional finish
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Do you need sand mastic in Great Linford?
Some old mastic was never deep enough. Mastic that’s too thin cracks and drops out so we make sure the new mastic is the right thickness.
Most people get in touch when they notice one of these:
- Modern sealant on a period surround
- Weathered mastic on the most exposed windows
- Draughts and rain around sash boxes
- Open joints round the window box
In the older streets around Church of St Andrew, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
Questions to ask before booking
- Is the old sealant removed completely?
- Whether the sealant suits the joint
- When the joint can take water or movement
- What happens if they find a problem under the old sealant

What sealant work can’t fix
New sealant can’t fix everything, and we’d rather say so up front. It will not solve:
- Decisions on consent for listed homes
- Sashes that rattle, stick or will not open
- Broken panes
If in doubt, ring 0345 464 0079 or send us an email and we will say what we think before booking.
Joints and surfaces we work on
- Brick reveals
- Tenement windows
- Sash and case windows
- Period & listed homes
- Timber door frames
- Stone surrounds
How it works
Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for a single window, longer for several. A visit to Great Linford is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We look at the surrounds with you and agree the joints to renew.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
Getting ready for the visit
- Clear the area around the work
- Let us know about earlier repairs to the joints
- Tell us if parking is tricky

Windows and doors in Great Linford
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. With historic houses such as Linford Manor (about 0.4 miles north-east) nearby, there’s older building stock in the area around Great Linford as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Letting a property close to Wolverton station? Then any sash windows need sound mastic to keep draughts and rain out. If you look after a building such as Great Linford Primary School, its window and door frames need their mastic kept sound, just like a home’s.

Leave it or put it right?
Draughts round a sash window are not always the sashes. Open mastic joints round the box can let air in and new mastic seals them. Homes in smaller places like Great Linford 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.
A failed joint rarely gets cheaper to fix by waiting. If you are unsure, ring 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.

Surface by surface
Tenement and terrace windows
In shared buildings, the windows may be part of a wider repair, so check who is responsible first.
Brick reveals
An open joint at a brick reveal lets weather in. Renewing the mastic closes it.
