Mastic sealing in Barkham, done properly
Owners and agents normally inherit a building’s mastic rather than choose it, and it ages quietly: window perimeters, door frames, external joints and communal junctions all rely on it. Once it cracks, hardens or comes away, draughts and water find a way in, and occupiers start reporting it. Site teams most often ask us about cracked, hardened mastic round windows on a block and estate-wide sealant that is simply worn out, on window and door perimeters on blocks, communal kitchens and washrooms and external wall and movement joints. A single leaking joint is often how a building in Barkham first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Around smaller places like Barkham, older walls fitted with newer windows are a familiar sight. Perimeter mastic there has to grip an uneven face and suit the building’s character.
A 12-month guarantee applies to all our work in Wokingham. If an installation problem shows up, phone 01277 525 020 or email drawings and photos and we will arrange a return visit.

Site staff or a sealant specialist?
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
When something else is needed
Before quoting, we check that sealant is the right answer. It won’t put right:
- Cracked or crumbling render, brick or stone at the joint edges (we’ll tell you if so)
- Broken glass or failed sealed units
- Frames that are rotten, warped or broken
If in doubt, call the office on 01277 525 020 or email a schedule or drawings and we will say what we think.

Mastic sealing around Barkham: what changes locally
Barkham is in the South East, one of the UK’s drier regions. Outside mastic still needs a dry joint and the right temperature, while the elevations that take the most sun tend to show hardened mastic first. Barkham lies roughly 34 miles out from central London. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres.
Blocks of flats and mixed-use buildings often cluster around stations such as Wokingham station (to the north-east of Barkham) and their window and balcony mastic tends to age at the same rate across a building. If your remit includes a building such as The Coombes Church of England Primary School, frame and door mastic can be programmed for the holidays. Landlords with units on estates such as Molly Millars Lane Industrial Estate, 1.5 miles east of Barkham, can bring frame, door and external mastic across several units into one programme.
Barkham is about 2 miles south-west of Wokingham, in Wokingham. We cover commercial sites throughout Barkham. Barkham is one of 42 places in Wokingham on our list. There’s a separate page for Reading, roughly 6 miles from Barkham.

Your questions answered
Will you take on work at estates like Molly Millars Lane Industrial Estate, close to Barkham?
Yes. Our area takes in Barkham and its surroundings, with estates and business parks such as Molly Millars Lane Industrial Estate included. Send details of the unit and the work through our quote form for a quick quote.
Can you quote for a block close to Wokingham station?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. We work to your notice and access arrangements.
Does weather matter for sealant work?
Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
What guarantee do you give on resealing?
A 12-month guarantee covers our work. It applies to our workmanship rather than damage or problems with the frames.
Do you work in Barkham?
Yes. We cover Barkham, and the simplest way to start is to phone 01277 525 020 or email a schedule or drawings.
When is resealing likely to be due?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
Do you check for asbestos in old sealant?
In older buildings, old mastic can contain asbestos. We ask for the asbestos register or survey before work starts and suspect material is tested first.
Leave it or put it right?
Reacting to every complaint means sending someone out block by block. Planned resealing covers a whole building or estate in one go and is simpler to manage and budget. Converted and older buildings near places like Barkham tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.

Advice
Looking after the joints
Problems stay small when the joints are checked regularly. In particular:
- Share the asbestos register when you send details
- List the paperwork your organisation requires when you send details
- Protect low-level joints in entrances
- Track which buildings were done and when
If paintable sealant was used, decoration can follow once it has cured. Non-paintable silicone shouldn’t be painted over.
Budgets are easier to plan when sealant is part of planned maintenance. We can quote buildings in priority order and work down the list.

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.
