About our mastic sealing in Maidenhead
Before work starts, most agents and landlords want the documents in order. For documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We are CHAS accredited and a Constructionline member, with public liability insurance. We work on window and door perimeters on blocks, communal entrances and stairwells and external wall and movement joints, and the failures we’re asked to look at most are brittle perimeter mastic across a building and leaks at window and door perimeters. Looking for mastic applicators who cover Maidenhead? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.
Older buildings in towns like Maidenhead have often had replacement windows fitted at different times, which leaves perimeter mastic of very different ages. A look at the whole building shows which joints need doing now.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Site staff or a sealant specialist?
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
What we are called out for in Maidenhead
UV and rain age external sealant. It stiffens, stops stretching and cracks most of all on the sunniest and most exposed elevations.
Most enquiries start with something like this:
- Draughts at frames across a block
- Brittle perimeter mastic across a building
- Damp patches beside frames
- The same joint failures repeated across a portfolio
Buildings close to stations like Maidenhead station (0.5 miles south-east of Maidenhead) are often flats over shops, with frame mastic to keep sound.

After the work
Cleaning and maintenance staff play a part too. Pass these on to them:
- Group repairs into a planned programme
- Prioritise elevations facing the weather
- Ask residents or tenants to report leaks and draughts early
- Check the asbestos register before any old mastic is disturbed
Where a paintable product was specified, it can be painted after curing. Silicone typically can’t be painted, so keep decorators off it unless told otherwise.
The longer failed joints are left, the more likely the substrate edges break up. Once that happens, repairs come before resealing and the job grows.

How a job runs
Occupied buildings need a little choreography. We sign and contain the area we’re in, with routes through the building left open and work section by section so the rest of the building stays in use. If you have more than one building in Maidenhead, they can often be done on the same visit, with one quote covering them. Give us your access times and we’ll fit the work in.
- We inspect the joints, building by building, and record what has failed and why.
- A fixed quote follows, split by block or building if that suits you.
- Dates, areas and access are agreed so residents or tenants can be told in advance.
- Failed mastic is removed and the faces taken back to sound, dry material.
- Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
- Finished joints are looked over and the 12-month guarantee confirmed.
Preparing the site
- Point out parking and an unloading spot
- Tell staff and tenants when we’ll be in
- Clear stock, furniture or equipment away from the joints
Getting a fixed quote

That varies with the scale of the job, though a typical visit usually takes a day or two for a single block, longer for an estate programme. For bigger or phased jobs, we’ll set out a timescale with the quote.
Is mastic sealing guaranteed?

How soon can the area be used again?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
