How we handle construction mastic in Twyford
The specification and the programme set the job rather than whatever product is to hand. Where the specification names a product, we use it; any alternative we suggest is put to you before anything changes. Joint widths, backing, primers and tooling follow the manufacturer’s guidance so the detail on the drawing is what ends up on site. We work on floor and skirting junctions, sanitary and kitchen joints and window and door perimeters, and the usual reasons a site gets in touch are bath and shower joints scraped during the final clean and frame perimeters left unsealed or poorly sealed. A single leaking joint is often how a building in Twyford 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 places like Twyford, a lot of construction is the conversion of older buildings, which leaves joints between old walls and new frames that need a sealant able to take the movement, in a colour the planners or architect are happy with.
We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant.

Our process
In a busy building, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed before we move to the next. If neighbouring businesses or buildings around Twyford need work too, visits can be combined. Mention the building’s opening times and we will work within them.
- First we take quantities off the drawings and read through the specification.
- A fixed quote sets out the scope, the products and the sequence.
- You tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we confirm it with the quote.
- Areas are sealed plot by plot or floor by floor as the trades hand them over.
- Every joint is prepared, set to depth and sealed with the specified product.
- Before handover, snags are dealt with and the package is signed off under our 12-month guarantee.
Getting the site ready
- For older buildings, check the asbestos register before work
- Point out parking and an unloading spot
- Tell us which areas need to stay in use

Doing it in-house
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
Surface by surface
Internal decorators’ caulk
Acrylic caulk fills internal gaps around trims, boards and frames ahead of decorating. It’s paintable and suits gaps that don’t move, and we use a flexible sealant where there’s movement.
Window and door perimeters
Frames sealed into the opening keep rain out of the reveal. They’re sealed with a low-modulus neutral-cure silicone or another product named in the specification and set the depth with backing where needed.
Construction mastic around Twyford: how the place shapes the job
Central London is about 33 miles from Twyford. Towns within reach of London tend to keep building, from flats to offices and schools, which keeps mastic packages in demand. Twyford sits in one of the drier corners of the country, the South East. Even so, frost and condensation on steel and glass are common on winter mornings, so the external programme keeps a little slack.
When units on a site such as Castle End Business Park (to the north-east of Twyford) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package. For contractors on a campus like University of Reading, 2.6 miles to the west of Twyford, facade and perimeter sealing has to fit around students and term dates.
Twyford is about 2 miles north-east of Woodley, in Wokingham. Across the RG10 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Twyford is one of 42 places we cover in Wokingham for mastic packages.
Commercial sites across RG10 are covered. If your site is on Station Road, High Street and London Road or close by, send details and we will quote for mastic packages. We also cover Ruscombe (1 mile north-east), Charvil (1 mile west), Whistley Green (1 mile south), Hare Hatch (1 mile north-east) and Hurst (2 miles south). Nearby towns on our patch include Wokingham (5 miles south), Earley (4 miles south-west), Crowthorne (8 miles south), Lower Earley (4 miles south-west), Winnersh (3 miles south) and Shinfield (6 miles south-west).
Local landmarks in Twyford
Around Twyford, our work takes us to commercial buildings near Loddon Nature Reserve, The Piggott School and Blessed Hugh Faringdon Catholic School, among other places. There’s a railway station in Twyford itself: Twyford station. Well-known places in the area include Royal Berkshire Hospital (4.5 miles south-west) and Frazer Nash Archives (3.8 miles north). Green spaces nearby include South Lake and Alder Moors.
Signs you need construction mastic in Twyford
Swapping the specified sealant for a cheaper general-purpose product is a common cause of failure. A general-purpose silicone on a facade or a caulk in a wet area won’t perform like the specified product. We stick to the specified product, or put any alternative to you first.
What tends to prompt an enquiry:
- A mastic package split between trades with no clear owner
- Failed sealant in an existing building being refurbished
- Mastic snags holding up handover
- New external sealant already peeling away
Projects at schools like Polehampton Church of England Infant School work to term dates, so mastic is programmed tightly.
Before you book anyone
- What site paperwork they can supply
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Do they follow the manufacturer’s priming guidance?
- Whether their applicators hold CSCS cards
What we can’t put right
Honesty saves time and money. New sealant won’t cure:
- Damage to finishes by other trades after we’ve sealed
- Glazing units that are cracked or misted
- Deciding which fire-stopping product a penetration needs
If you are not sure, just speak to us on 01277 525 020 or email the details over and we’ll give you a straight answer before you book.

Twyford: questions and answers
Will you plan work around the academic year at somewhere like University of Reading?
Yes, holiday working periods are the norm on campus jobs. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Is hospital work, at somewhere like Royal Berkshire Hospital, something you do?
Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Does the weather affect the work?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
Do you take on multi-site work?
Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.
Is Twyford in your area?
Yes. Twyford is in our area and the rest of Wokingham. For a quote, give us a call on 01277 525 020 or use the quote form.
Are you fully insured?
Yes. Mastic Doctor is fully insured, public liability included.
Can the building stay open while you work?
In most cases, yes. We phase the work so most of the building stays in use, with each area protected and signed.
