About our construction mastic in Three Mile Cross
Site managers want applicators who turn up with the right cards and paperwork. Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member, with public liability insurance in place. RAMS, an insurance certificate and CSCS details can be confirmed with the quote if you tell us what you need. We work on brick and block movement joints, window and door perimeters and internal decorators’ caulk, and what we’re called in for most is missed perimeter joints on a new elevation and old sealant on a refurbishment that needs stripping before new work. Whether you call it commercial sealant work, mastic application or joint sealing, in Three Mile Cross it comes down to the same thing: the right product in a properly prepared joint.
For a site near Three Mile Cross, the mastic visit is planned so the right sealants, primers and backing rod are on hand. Drawings, photos and the programme let us give a fixed quote.
A 12-month guarantee applies to all our work in Wokingham. If an installation problem shows up, give us a call on 01277 525 020 or use the quote form and we’ll arrange a return visit.

What the job involves on each surface
External facade and movement joints
Movement joints in the facade are sealed with a product suited to the expected movement. Depth is controlled with backing rod so the bead bonds to two sides only.
Fire-rated sealant where specified
Fire-rated sealant forms part of some packages, installed to the product’s tested detail where it is specified. Fire stopping design belongs to the designer and building control and we install what’s specified.
What sealant work can’t fix
Honesty saves time and money. New sealant won’t cure:
- Joint design decisions that belong to the architect or engineer
- Damage to finishes by other trades after we’ve sealed
- Frames fitted out of tolerance
Not sure which it is? You can speak to us on 01277 525 020 or email us and we will tell you honestly before you book.

Facades, frames and programmes in Three Mile Cross
Three Mile Cross is in the South East, one of the UK’s drier regions. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so the external programme keeps a little slack. A 2-mile radius around Three Mile Cross takes in a number of hotels. Hotel extensions and refits typically have to fit around bookings, so mastic dates are tight.
With historic properties like Stratfield Saye House (4 miles south of Three Mile Cross) in the area, refurbishment work often meets old masonry that needs compatible sealants. Building work at universities like University of Reading - Whiteknights Campus (to the north-east of Three Mile Cross) is often timed for the summer, mastic included.

For managing agents and facilities managers
Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.
Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.
When to call us in Three Mile Cross
Value-engineered products sometimes end up in the wrong joints. A sealant that isn’t right for the substrate or the movement will fail ahead of time. We stick to the specified product, or put any alternative to you first.
Clients normally get in touch after noticing something like this:
- Early adhesion failures on new external joints
- A long mastic snag list close to completion
- Oversized or tapered gaps around new frames
- Caulk cracking where joints are moving more than expected
On a healthcare site such as Berkshire Independent Hospital, 2.8 miles to the north of Three Mile Cross, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.
What your quote should include
- Who will actually carry out the work
- Whether primer will be used where the manufacturer specifies it
- How long is the guarantee, and what does it include?
- Their pre-qualification and accreditations
Looking after the joints
A few simple habits keep the new joints working:
- Release areas for mastic once other trades have finished in them
- Ask cleaners to use soft cloths around fresh sealant
- Protect sealed areas from following trades
- Allow flexibility for external sealing in damp or cold weather
Tell the builders’ clean team which areas have new sealant. Blades and abrasive pads are the commonest cause of damage at the final clean.
External joints sealed in poor weather are a common cause of early failure. Waiting for a dry joint and the right temperature is better than redoing work.
FAQs: Three Mile Cross
Can work at a site such as University of Reading - Whiteknights Campus fit around teaching?

Yes, sites like Reading International Business Park are within our area, along with the rest of Three Mile Cross. Photos and a short description are enough for a first look.
Can you work while the building is occupied?
Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.
What site paperwork can you supply?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
What do you charge?
Every job gets its own fixed quote. To get one, speak to us on 01277 525 020 or send photos by email.
Are you CHAS accredited?

How do you deal with asbestos in old sealant?
Managing asbestos is the dutyholder’s responsibility, so we will ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.
