Botany homes and the weather
Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic. Under the Tenements (Scotland) Act 2004, shared parts of a tenement, such as the roof and outside walls, are looked after by the owners together, and many buildings use a factor to arrange it. Windows generally belong to the flat, but the title deeds have the final say.
Historic houses such as Tenement House, about 1.8 miles south-east, show how far back building around Botany goes, and older homes nearby need a sealant that suits their walls. Managing a site like Cleveden Secondary School? Then larger buildings have plenty of frames, and the mastic around each one ages.

Sand mastic for homes and businesses in Botany
Sand mastic suits most period window surrounds. Newer frames usually get a flexible sealant instead, and we’ll talk through which suits your home. We work on period & listed homes, brick reveals and sash and case windows, and people most often call us about gaps between timber frames and stone or brick and mastic dropping out of the joint.
Older stone-built tenements in Scotland’s cities were built with sash and case windows, though many have since been replaced. Whether you’re in a tenement flat or a house in Botany, the joint between frame and wall is what keeps the weather out.
You’re covered for a year from the day we finish. If there’s a problem with it, please drop us a line at info@mrmastic.co.uk.

For landlords and businesses
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.
Mouldy or split sealant often shows up at the end of a tenancy. Several properties can go on one quote.
Can I do it myself?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
