Mastic sealing in Slough Green, done properly
For over 20 years we have resealed joints for owners, agents and landlords. Every applicator holds a CSCS card and we hold public liability insurance. Resealed mastic joints in Slough Green carry our 12-month guarantee. Most enquiries involve draughts at frames across a block and open joints in brickwork or panels, across communal kitchens and washrooms, window and door perimeters on blocks and communal entrances and stairwells. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Slough Green it comes down to the same thing: the right product in a properly prepared joint.
In and around smaller places like Slough Green, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Frame and wall-joint mastic on all of them ages and hardens.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Cost factors for mastic joints
These are the things that shape the price:
- Travel to remote or island sites
- Whether old sealant has to be cut out first
- Joint width, depth and condition
- Site requirements such as inductions and permits
The price depends on the quantity of joints, how much old material needs removing and how the joints are reached. Call for a quote once you have the details.
What we need to price the job
The more we know, the firmer the quote. Helpful details to send:
- Your programme or deadline
- The asbestos register, for older buildings
- The type of building and who uses it
- How the joints are reached, and at what height
Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. For smaller jobs, photographs and a description will do.

For managing agents and facilities managers
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.
Whether you’re a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.
Maintenance after handover
After handover, a little attention goes a long way:
- Keep a record of when each building was resealed
- Make mastic part of routine maintenance checks
- Start inspections with the most exposed faces
- Group repairs into a planned programme
Ask residents or tenants to report draughts or leaks round windows early. A quick report keeps a small repair small.
Budgets are easier to plan when sealant is part of planned maintenance. A programme can start with the worst buildings and work down the list.
Our process
When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work normally takes a day or two for a single block, longer for an estate programme. For a building around Slough Green, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.
- We inspect each building and record the joints that have failed.
- You get a fixed quote, per block or for the whole programme.
- We agree the programme and dates with you.
- Old mastic is removed and the joint faces prepared.
- New sealant goes in with backing rod and primer where needed.
- Each building is checked and signed off with the 12-month guarantee.
Getting the site ready

- Explain the parking and delivery arrangements
- Have the specification and drawings to hand

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, so we check the asbestos register or survey first. Suspect material is tested before work continues.
Questions about Slough Green
Can you work at a site such as Crosspot Industrial Estate, by Slough Green?
Yes. We cover Slough Green and the area around it, including industrial estates, business parks and retail parks such as Crosspot Industrial Estate. Send details of the unit and the work through our quote form for a quick quote.
We manage a building near Balcombe station. Can you help?
Yes, we work for agents, landlords and housing associations with blocks of every size. Photos of each elevation help us quote accurately.
Can you send RAMS and CSCS details before starting?
We are CHAS accredited, a Constructionline member and carry public liability insurance. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
Do you work to architects’ specifications?
Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it.
Can weather delay the job?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
Do you guarantee the mastic work?
Every building we reseal has a 12-month guarantee. It covers our workmanship, not later building movement, damage or frame failures.
How do you reach windows on upper floors?
Every block is different. We agree access with you at quote stage so the fixed quote reflects it.
What happens if it’s left?
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. Around Slough Green, it’s better to renew all the failing joints at once, rather than one at a time. Send photographs of each area and we’ll quote for the lot.
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote and we will explain how it’s made up.
What you get with us
- Failed material removed, not covered up
- Clear, fixed quotes
- Colour agreed before work starts

Outside mastic still needs a dry joint and the right temperature, and elevations facing the sun and the prevailing weather are usually where frame mastic ages first.
