DIY sealant or a professional job?
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, and the work is guaranteed for a year.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Is consent needed for window work on a listed home?
Yes, it’s worth checking. Ask your local planning authority whether consent is needed for listed or conservation-area properties.
Can I paint the new mastic?
The usual advice is to leave sand mastic unpainted. Ask us before you decorate around it and we’ll advise.

That depends on your windows. Period windows in stone or brick normally suit sand mastic, while modern frames normally get a flexible sealant.

What sand mastic looks like in Causeway End
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Homes close to Church of the Holy Cross include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

What happens if it’s left?
A silicone bead can be quicker, but it can look wrong on a period surround. Sand mastic suits the building and blends with the stone or brick. Around Causeway End, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
The cost depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before we start.
