Window mastic for homes and businesses in Grayswood

Most frames have an outside joint and an inside one. Outside, the mastic keeps rain out; inside, the joint between frame and plaster stops draughts and tidies the reveal. Either or both can be done. We work on composite doors, timber windows & doors and window sills, and people most often call us about mastic that has split away from the wall and cracked sealant at the sill ends.

Mastic can only go onto a dry, clean joint, so window work in Grayswood is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.

You’re covered for a year from the day we finish. If anything is not right with it, phone 0345 464 0079 or email us.

What the job involves on each surface

Timber windows & doors

Wood swells when it’s wet and shrinks when it dries, so a flexible sealant is essential. The paint or stain needs to be sound where the sealant meets it.

Patio & French doors

Water at the foot of a door frame isn’t always the mastic: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We check before we reseal.

Aftercare tips

After the cure time, these simple habits help:

Don’t aim a pressure washer at the joints
Keep solvents and bleach off the sealant
Clean frames with a soft cloth and soapy water
Clear any debris from frame drain holes

A yearly look round the frames is enough. Cracks and lifting edges are easy to spot early, and if anything looks wrong, just phone 0345 464 0079 or drop us an email.

A failed joint lets water into the wall a little at a time. Often the first sign is a damp patch inside or flaking paint on the reveal. Catching it early keeps the fix to a reseal.

Grayswood homes and the weather

The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

If you live in an older home near All Saints' Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Schools such as Grayswood Church of England (Aided) Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

Can I do it myself?

If you are 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.

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
