Advice
Sand mastic for homes and businesses in Fairlands
On many period windows, sand mastic looks right and suits the building. On modern frames we’d normally use a flexible sealant, and we’ll talk through which suits your home. Common call-outs are for mastic dropping out of the joint and mastic that needs renewing before redecorating, across tenement windows, brick reveals and period & listed homes.
Mastic can only go onto a dry, clean joint, so window work in Fairlands is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
Each job carries a 12-month guarantee, large or small.

FAQs for Fairlands
Can you help a landlord with a rental near Guildford station?
Yes, we work for landlords and agents. You can ring 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before we start.
Do you cover Fairlands for sand mastic?
Yes. We work across London and the South East, and Fairlands is part of that. You can call 0345 464 0079 or drop us an email and tell us what needs doing, and we’ll send you a clear quote.
Can sand mastic be painted?
It’s traditionally left unpainted, as guidance on traditional windows advises. Ask us before decorating.
Will you leave a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Do you do commercial work?
Yes, regularly. Larger jobs can be planned room by room or area by area to suit the site.
How long does sand mastic take to go off?
It takes a while. The skin forms first, and the full set comes later, and we will tell you what to expect.
Do you guarantee sand mastic work?
Our 12-month guarantee covers every job, sand mastic included.
Leave it or put it right?
Before painting the windows, it pays to renew the mastic. Paint over cracked mastic won’t stop the gaps, and the new mastic is traditionally left unpainted. In a small place like Fairlands, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or email us and we’ll talk you through it.

Landlord and commercial work in Fairlands
We work for landlords and letting agents as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order.
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.
Fairlands homes and the weather
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. Historic houses like Guildford Castle (about 2.8 miles south-east) are a reminder that the area around Fairlands has older buildings as well as new. 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.
If you let a flat or house near Guildford station, any sash windows need sound mastic to keep draughts and rain out. In the older streets around St Alban's Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Other services in Fairlands
Do you need sand mastic in Fairlands?
Timber frames move with the seasons. That movement opens up the mastic joint over time.
Signs it’s time to call us include:
- Wind and rain getting in round a sash window
- Gaps where the frame meets the masonry
- Tired mastic found when preparing windows for paint
- Crumbling sand mastic round a window
If you look after a building such as Worplesdon Primary School, the mastic around its windows and doors needs looking after like any other building’s.

DIY versus a professional finish
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
What a professional job adds is preparation and the right 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.
