What sealant work cannot fix

- Broken panes
- Sashes that rattle, stick or won’t open
- Crumbling stone or brickwork round the window

Sand mastic for homes and businesses in Cross Lane
Sand mastic suits most period window surrounds. Newer frames generally get a flexible sealant instead and we will explain which is best for yours. We work on sash and case windows, timber door frames and period & listed homes, and the jobs we see most are silicone on a period window that looks wrong and gaps round a timber door in stone or brick.
Around Cross Lane, conservatories, garden rooms and patio doors are often part of the house. Their glazing joints and frame seals are as much a part of the job as the windows.
You are covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or drop us an email.

Aftercare tips
No joint lasts for ever, but care makes a real difference. Our tips:
- Inspect the joints round the windows every year or so
- Plan mastic work ahead of painting
- Get any rot dealt with first
- Don’t paint over the new mastic
Look at the mastic when you look over the windows. Small cracks are easier to deal with early.
Good mastic helps keep the frame dry. Failed mastic lets water reach the timber and timber that stays wet can rot.

Stone surrounds
We take care not to mark the stone while raking out the old mastic.
Sash and case windows
A sash window’s box frame sits in the masonry opening. The gap round it is pointed with sand mastic.
DIY sealant or a professional job?
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Common questions in Cross Lane
Is Cross Lane in your area for sand mastic?
Yes, Cross Lane is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or drop us an email and tell us what needs doing.
Is Cross Lane within the area you cover?
Yes, Cross Lane is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Can I choose the sealant colour?
Usually, yes. White, clear and grey are common, and other colours are available for many products, and we’ll agree it with you first.
Is sand mastic better than silicone for my windows?
It depends on the window. On many period windows, sand mastic looks right and suits the building, while modern frames normally get a flexible sealant.
Is consent needed for window work on a listed home?
Your local planning authority is the one to ask. They’ll tell you if consent is needed.
Can tenants book the work?
Yes. Ask your landlord first, and we can send them the quote if that helps.
Do I have to be there?
It depends on the job. For work indoors, someone needs to let us in.
Will there be a smell?
Possibly a little. It fades as the sealant cures.
Leave it or put it right?
New mastic over crumbling mastic won’t hold. Raking out and preparing the joint gives it a sound base so the new work lasts. Homes in smaller places like Cross Lane can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or send us an email.

What happens on the day
A visit follows a simple pattern: we look at the joints together, protect the area around them, carry out the job and clear up. Most jobs take a few hours for a single window, longer for several. A visit to Cross Lane is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic is not too thick.
- New sand mastic is applied and shaped by hand.
- The finish is dressed neatly.
Before we arrive

Advice
Windows and doors in Cross Lane
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. Historic houses like Carisbrooke Castle (about 1.7 miles south-west) are a reminder that the area around Cross Lane has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
For site and facilities teams at buildings such as Summerfields Primary School, its window and door frames need their mastic kept sound, just like a home’s. In the older streets around St Paul's Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
