Tidmarsh: questions and answers
Do you work for managing agents with blocks near Pangbourne station?
Yes, we work for agents, landlords and housing associations with blocks of every size. Give us the building’s details and say how residents are notified, and we’ll quote and plan to suit.
Does your area include sites such as Turnhams Green Business Park, near Tidmarsh?
Yes. We cover Tidmarsh and the area around it, including industrial estates, business parks and retail parks such as Turnhams Green Business Park. To start, just call 01277 525 020 or email us with the unit, the joints involved and your access times.
How many days will you need on site?
The duration is planned around your programme and the access we’re given. You’ll have an expected duration with the quote.
Is mastic sealing guaranteed?
Our workmanship carries a 12-month guarantee and we hold public liability insurance.
Do you work to architects’ specifications?
Yes. Include it with the drawings when you ask for a quote, and we will price the work to it, flagging anything that needs clarifying.
What if the old mastic contains asbestos?
Some mastics in pre-2000 buildings contain asbestos. We ask for the asbestos register or survey before work starts and suspect material is tested first.
How long do sealant joints last?
Nobody can honestly give a figure in years, 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.
About our mastic sealing in Tidmarsh
Our clients include managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios. Many prefer a planned programme to one-off visits and we quote and schedule each building in turn. Most enquiries involve occupiers reporting cold air round windows and damaged joints in communal entrances and corridors, on balcony and threshold joints, window and door perimeters on blocks and communal kitchens and washrooms. Most enquiries from Tidmarsh start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
For owners with a single building near Tidmarsh, we plan to finish in one visit where possible. Photos of each elevation help us quote accurately.
We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant.

Honest limits
A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is one of these:
- Materials that need asbestos testing before work
- Cracked or crumbling render, brick or stone at the joint edges (we will tell you if so)
- Roof leaks, gutters or failed flashings that aren’t sealant joints
Not sure which it is? You can call the office on 01277 525 020 or send photos by email and we will tell you honestly.

Why deal with it now?
Replacing mastic before water gets in is a planned job. Once water has tracked in, the repair list grows and occupiers notice. Older rural buildings around Tidmarsh move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
There’s no price list, since every building and every scope is different. Call for a quote and we’ll price your job on its own details.

Different surfaces, different methods
Window and door perimeters on blocks
On most blocks, the frame-to-wall joint is where failure shows first. We remove the failed mastic, prepare the faces, add backing rod if the joint is deep and reseal.
Tenement and older buildings
Older mastic can contain asbestos and the register is checked before anything is disturbed. Suspect material is tested before work continues.
Aftercare for building managers
Cleaning and maintenance staff play a part too. Pass these on to them:
- Share the asbestos register when you send details
- Group repairs into a planned programme
- Start inspections with the most exposed faces
- Protect low-level joints in entrances
Keep records of when each building was resealed. That makes future programmes easier to plan and shows what was done.
Planned resealing is easier to budget than emergency repairs. A programme can start with the worst buildings so spending is spread.
Frames, entrances and external joints in Tidmarsh
Tidmarsh is about 43 miles from central London. Within reach of London, blocks run by agents and associations are common around stations, and window and balcony mastic on them tends to age at the same rate. Tidmarsh sits in one of the drier corners of the country, the South East. Outside mastic still needs a dry joint and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first.
Trustees of buildings like Church of St Laurence can bring frame and external mastic into a planned maintenance list. Property owners at sites such as Turnhams Green Business Park, 2.1 miles to the south-east of Tidmarsh, can have mastic renewed between lettings.
Tidmarsh is about 5 miles west of Reading, in West Berkshire. We cover commercial sites throughout Tidmarsh, whether it’s a single job or part of a planned programme. 140 places across West Berkshire fall within our area, Tidmarsh among them.

We also cover Sulham (1 mile east), Pangbourne (1 mile north), Whitchurch-on-Thames (1 mile north), Little Heath (2 miles south-east) and Englefield (2 miles south) for mastic joints.

What’s near Tidmarsh
Recent enquiries here include premises near The Cross Keys pub and Denefield School. For rail, the closest station is Pangbourne station, about 1.1 miles north of the centre.

When to call us in Tidmarsh
In communal areas, joints take knocks from bins, bikes, buggies and deliveries, with joints near the floor and around doors suffering most. Cleaning products add to the wear.
Common reasons buildings call us in:
- Estate-wide sealant that is simply worn out
- Damp patches beside frames
- Old repairs sealed over failed mastic
- No planned programme for sealant
With historic buildings such as Mapledurham House, 2.5 miles north-east of Tidmarsh, in the wider area, owners of older properties around Tidmarsh should expect mastic to need a product that suits old masonry.
