About our mastic sealing in Henley-on-Thames
Different joints need different sealants. Window perimeters and external joints often take a low-modulus neutral-cure silicone, and MS polymer sealants stick well to many substrates and often take paint. We’ll confirm the colours available for the specified product. If you have open joints in brickwork or panels and estate-wide sealant that is simply worn out, we can put it right, on external wall and movement joints, balcony and threshold joints and shopfronts below residential blocks alike. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Henley-on-Thames is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
For landlords and associations with stock in and around Henley-on-Thames, grouping buildings into one visit saves travel. One quote can cover a whole list of addresses.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Keeping the joints sound
For the best life from the joints:
- Look at the sunniest and most exposed elevations first
- List the paperwork your organisation requires when you send details
- Reduce knocks to communal area joints
- Log resealing dates block by block
Protect entrance and corridor joints from knocks where possible. Damage at low level is the most common reason communal joints fail early.
Leaks at window perimeters spoil finishes and can affect frames. Resealing early keeps the job small.
Your questions answered
We manage a building near Henley-On-Thames station. Can you help?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Give us the building’s details and say how residents are notified, and we’ll quote and plan to suit.
Can you quote for mastic across several buildings in and around Henley-on-Thames?
Yes, we quote for single buildings and for programmes across several blocks. We can phase the programme to suit your budgets and notice periods.
Will residents or tenants be disturbed?
Residents and tenants carry on as normal. We flag any areas that need internal access well before the dates so you can arrange it with occupiers.
Do you work to architects’ specifications?
Yes. Send it with your enquiry, and we will price the work to it.
Is mastic sealing guaranteed?
Every building we reseal has a 12-month guarantee. It applies to our workmanship rather than damage or problems with the frames.
How soon can the area be used again?
That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we will confirm the curing time on the day.
How do you reach windows on upper floors?
Every block is different. We agree access with you at quote stage so there are no surprises.
What sealant work can’t fix
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:
- Frames that are rotten, warped or broken
- Masonry that has broken away beside the joint
- Leaks from above rather than through a joint
If in doubt, call 01277 525 020 or send details through our quote form and we’ll say what we think before you book.
Surfaces we seal
- Shopfronts below residential blocks
- Window and door perimeters on blocks
- Communal kitchens and washrooms
- External wall and movement joints
- Balcony and threshold joints
- Communal entrances and stairwells
Owners, agents and contractors
Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

From enquiry to sign-off
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. Then we strip out anything that has failed, prepare every joint and seal it. If neighbouring businesses or buildings around Henley-on-Thames need work too, visits can be combined. Mention the building’s opening times and we will work within them.
- Each block or building is walked and the failed joints recorded with the likely cause.
- You get a fixed quote, priced per building where that helps your budgeting.
- The programme is fixed with you, including dates you can pass on to residents or tenants.
- Old sealant is stripped and each face prepared back to firm material.
- Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
- Finished joints are looked over and the 12-month guarantee confirmed.
Getting the site ready
- For older buildings, check the asbestos register before work
- Explain the parking and delivery arrangements
- Tell staff and tenants when we will be in

Site staff or a sealant specialist?
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.
