About our mastic sealing in Wentworth
Treatment starts with a proper look: what has failed, what caused it and whether new sealant will actually solve it. Failed mastic is stripped, the faces taken back to sound material, primed where the manufacturer specifies and resealed, with backing rod setting the depth where it’s needed. We work on shopfronts below residential blocks, window and door perimeters on blocks and communal kitchens and washrooms, and the failures we’re asked to look at most are a mix of products and colours from past repairs and movement joints with sealant missing. Whoever orders the work in Wentworth, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.
Owners and agents with buildings around smaller places such as Wentworth tend to manage small terraces of association properties, converted barns and commercial units. Frame and wall-joint mastic on all of them ages and hardens.
Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Building owners, agents and FMs in Wentworth
As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We’re fully insured, and our insurance certificate can go with the quote.
For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.
Why deal with it now?
A bead run over old mastic can look like a repair. It won’t grip the old sealant and soon comes away. Full removal and proper preparation is what lasts. Halls, stores and units around places like Wentworth may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.

What the job involves on each surface
Planned maintenance
Planned resealing replaces emergency callouts and spreads the work.
Tenement and older buildings
Older buildings, including Scotland’s sandstone tenements, have their own joint details. The material either side of the joint shapes the product choice.
Mastic sealing around Wentworth: what changes locally
The South East is one of the drier parts of the UK. Outside mastic still needs a dry joint and the right temperature, and elevations facing the sun and the prevailing weather are typically where frame mastic ages first. Central London is about 22 miles from Wentworth. Managed blocks of flats are a big part of commuter-belt property.
If your remit includes a building such as Christ Church CofE Aided Infant School, frame and door mastic can be programmed for the holidays. Trustees of buildings like Christ Church can bring frame and external mastic into a planned maintenance list.
