About our mastic sealing in Streatley
Managing agents and housing associations normally need paperwork before anyone starts. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We’re a Constructionline member and CHAS accredited, and we carry public liability insurance. We work on shopfronts below residential blocks, communal entrances and stairwells and external wall and movement joints, and the failures we are asked to look at most are movement joints with sealant missing and leaks at window and door perimeters. Most enquiries from Streatley 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.
Owners and agents with buildings around smaller places such as Streatley tend to manage small terraces of association properties, converted barns and commercial units. Mastic around frames and on external joints wears out in time, whatever the building.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

How a job runs

If others near Streatley need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

Questions we’re asked in Streatley
Is Streatley too small for you to travel to?
No. Places such as Streatley are covered as much as the big towns. We cover Greater London and the counties of the South East. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
Do you take on block-wide or estate-wide mastic work in Streatley?
Yes, we quote for single buildings and for programmes across several blocks. Send the addresses and photographs and we’ll give a fixed quote.
How long does a typical visit take?
It depends on the scope, but the work typically takes a few days for most blocks, with larger programmes scheduled building by building. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.
Can weather delay the job?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.
Do you check for asbestos in old sealant?
Asbestos removal isn’t part of our work. Anything suspect is tested before we carry on, and the duty to manage asbestos sits with the dutyholder.
What paperwork can you provide?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We hold CHAS accreditation and Constructionline membership.
How do you choose the sealant?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Should maintenance staff do it?
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.
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Do you need mastic sealing in Streatley?
We often find joints filled solid with no backing rod, so the mastic is glued to the joint bottom too. That three-sided adhesion stops it stretching and splits as the building moves.
It’s worth sending us details if you spot any of the following:
- Occupiers reporting cold air round windows
- Patchy repairs in mismatched sealant
- Estate-wide sealant that is simply worn out
- Repeated reactive repairs to the same buildings
Churches, halls and community buildings such as Church of St Mary are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.

What affects the price in Streatley
Before we quote, we look at:
- Whether the work must be split into stages
- How much existing material needs removing
- Location, for remote and island sites
- Access and working height
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.
What we need to price the job
We can often quote from photos and a few details. Please tell us:
- Rough lengths or quantities, or drawings if you have them
- The site address and postcode
- Your programme or deadline
- Anything awkward about access or site hours
Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.
Surface by surface
External movement joints
The joint width has to suit the movement and the sealant’s capability with the width-to-depth ratio set as the manufacturer advises.
Communal areas
Communal areas stay in use while we work. We work in sections so access is never blocked.
Keeping the joints sound
Regular inspection catches problems early. In particular:
- Group repairs into a planned programme
- Ask residents or tenants to report leaks and draughts early
- Prioritise elevations facing the weather
- Include mastic in your cyclical inspections
Where a paintable product was specified, it can be painted after curing. Silicone typically can’t be painted, so keep decorators off it unless told otherwise.
Joints on a building age together, so it pays to look at the whole elevation. Doing them together saves going back again and again.
Blocks and managed buildings in Streatley
Streatley is in the South East, one of the UK’s drier regions. Outside mastic still needs a dry joint and the right temperature, and elevations facing the sun and the prevailing weather are typically where frame mastic ages first. At about 45 miles from central London, Streatley is within reach of the capital. Within reach of London, blocks run by agents and associations are common around stations; their frame mastic often ages block-wide.
Buildings close to stations like Goring & Streatley station, 0.8 miles to the east of Streatley, are often flats over shops, with frame mastic to keep sound. For a school such as Streatley C.E. Voluntary Controlled School, perimeter mastic on windows and doors is a holiday job.
