How we handle mastic sealing in Mortimer
In buildings from before 2000, some old mastics contain asbestos. We check the asbestos register or survey before any old sealant is cut out, and work stops for testing if there’s any doubt. We don’t remove asbestos-containing materials. If you are dealing with communal area joints that look neglected and damp patches beside frames, we can help, on external wall and movement joints, balcony and threshold joints and shopfronts below residential blocks alike. A single leaking joint is often how a building in Mortimer 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.
For landlords and associations with stock in and around Mortimer, grouping buildings into one visit saves travel. Send the addresses and photographs and we’ll quote for all of them together.
Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Work for main contractors and building owners
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.
Main contractors use us as their sealant subcontractor. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.
Planned mastic for Mortimer portfolios
At about 43 miles from central London, Mortimer is within reach of the capital. Managed blocks of flats are a big part of commuter-belt property. Rainfall across the South East, Mortimer included, is lower than in many parts of the UK. Outside mastic still needs a dry joint and the right temperature, and elevations facing the sun and the prevailing weather are normally where frame mastic ages first.
Historic properties like Stratfield Saye House, 3.6 miles south-east of Mortimer, show the age of some local stock, where frame mastic must suit soft brick or stone. If you are responsible for a building such as Mortimer Methodist Church, frame and door mastic needs the same attention as any other property.
Mortimer is about 4 miles north-east of Tadley, in West Berkshire.

On site: what to expect
We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. What matters most for a job in Mortimer is a clear list of what needs doing, so send photographs of each area. You will then get a fixed price for the work.
- A building-by-building inspection lists the failed joints.
- The quote is fixed and split as suits you.
- We agree the programme and dates with you.
- Failed sealant is removed and the faces prepared.
- Joints are resealed and tooled.

Advice
Common problems we fix in Mortimer
Frames, panels and masonry expand and contract through the year, and every joint has to stretch and squeeze with them. A joint that was too narrow, too thin or the wrong product can’t cope and fails early.
If one of these sounds familiar, it’s time for a closer look:
- A mix of products and colours from past repairs
- Open joints in brickwork or panels
- Water getting in round frames after rain
- Mastic failing across several blocks on an estate
Landlords with units on estates such as Stacey Industrial Park, 2.9 miles south-west of Mortimer, can bring frame, door and external mastic across several units into one programme.
What your quote should include
- Can the work be phased to keep areas open?
- Their approach to joint depth and backing
- How they handle RAMS and site documents
- Their public liability cover

What the job involves on each surface
Window and door perimeters on blocks
Blocks have a mix of frame materials, and the product is matched to the frame material and the masonry. We’ll confirm the colours available for the specified product.
Commercial and mixed-use buildings
Mixed-use buildings combine shops below with flats or offices above, so phasing has to suit both. Tell us your site hours and access windows and we’ll plan around them.
Questions we are asked in Mortimer
Is Mortimer too far out for you?
Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Good photos up front let us bring everything on the first visit.
Is Stacey Industrial Park, near Mortimer, within your area?
Yes. Our area takes in Mortimer and its surroundings, with estates and business parks such as Stacey Industrial Park included. A few photos and the unit address let us price the work.
Which sealant will you use?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.
Can you quote from photos?
Many jobs can be quoted from photos, drawings or a joint schedule. If the job needs a look first, we’ll arrange a visit.
How do you handle work on occupied blocks?
Occupiers stay in the building throughout. If any flats or units need access, we will tell you in advance so you can arrange it with occupiers.
Do you check for asbestos in old sealant?
We don’t remove asbestos-containing materials. If old sealant is suspected, work stops until it’s tested in line with the dutyholder’s asbestos management.
Should maintenance staff do it?
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
Leave it or put it right?
Leaving failed external joints lets water reach the structure behind. Damp patches, stained plaster and decorating claims can follow, which is harder to deal with than resealing. A failed joint lets water into a building whatever its size. Early resealing avoids the damage that follows a leak.
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
