Mastic sealing for commercial buildings in Checkendon
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, with each block quoted and scheduled in turn. The enquiries we see most involve complaints coming in block by block and old repairs sealed over failed mastic, on communal kitchens and washrooms, balcony and threshold joints and communal entrances and stairwells. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Checkendon is the same: the right product in a properly prepared joint.
Owners and agents with buildings around smaller places such as Checkendon 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.
We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant.

Aftercare for building managers
To get the most from the new sealant:
- Keep bins and bikes away from communal door frames
- Have the asbestos survey to hand for older buildings
- Track which buildings were done and when
- Prioritise elevations facing the weather
Keep records of when each building was resealed. It helps plan the next round and gives you a history.
Joints on a building age together, so it pays to look at the whole elevation. A planned reseal saves repeated visits.

Why act early in Checkendon
Resealing ahead of leaks keeps it to a maintenance task. After water has got in, there may be damp, damaged plaster or decoration to put right too and occupiers notice. Older rural buildings around Checkendon 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.
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote.

Related advice
For owners and agents in Checkendon
At about 41 miles from central London, Checkendon is within reach of the capital. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres. Checkendon sits in one of the drier corners of the country, the South East. Outside work still depends on dry joints, and south- and west-facing elevations, which take the most sun and rain, often age first.
For agents with blocks near Goring & Streatley station, which lies south-west of Checkendon, a block-wide mastic programme deals with frames, balconies and entrances in one go. If your remit includes a building such as Checkendon Church of England (A) Primary School, frame and door mastic can be programmed for the holidays.

Common problems we fix in Checkendon
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.
Common reasons buildings call us in:
- Movement joints with sealant missing
- Patchy repairs in mismatched sealant
- Damaged joints in communal entrances and corridors
- Mastic failing across several blocks on an estate
Landlords with units on estates such as Vanalloys Business Park (0.9 miles east of Checkendon) can bring frame, door and external mastic across several units into one programme.
Comparing quotes
- Proof of insurance
- What site paperwork they can supply
- Do they follow the manufacturer’s priming guidance?
- How long is the guarantee, and what does it include?
Should maintenance staff do it?
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.
Questions we are asked in Checkendon
Is Checkendon off your patch?
No. Places such as Checkendon are covered as much as the big towns. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.
We manage a building near Goring & Streatley station. Can you help?
Yes. Blocks of any size are within what we do. Photos of each elevation help us quote accurately.
Can you follow the specification on our project?
Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it, flagging anything that needs clarifying.
How many days will you need on site?
The duration is planned around your programme and the access we are given. You’ll have an expected duration with the quote.
What paperwork can you provide?
We’re CHAS accredited, a Constructionline member and carry public liability insurance. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
What guarantee do you give on resealing?
There is a 12-month guarantee on our workmanship and we hold public liability insurance.
Does weather matter for sealant work?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
