How the job changes by surface
Tenement and older buildings
Natural stone can be marked by the wrong sealant and we choose accordingly.
External movement joints
Joint size and product are matched to the expected movement, often around 2:1 width to depth, as the manufacturer advises.
Mastic sealing in Nash
For over 20 years we have resealed joints for owners, agents and landlords. Our applicators are CSCS-carded, and the work is backed by public liability insurance. Each building we complete carries a 12-month guarantee on our workmanship. If you are dealing with complaints coming in block by block and patchy repairs in mismatched sealant, we can put it right. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Nash, preparation and product choice get the time they need.
In and around smaller places like Nash, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Mastic around frames and on external joints wears out in time, whatever the building.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

What we can’t put right
Honesty saves time and money. Fresh joints won’t solve:
- Misted or failed double-glazed units
- Leaks through the frame itself rather than the perimeter
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
If in doubt, call 01277 525 020 or email a schedule or drawings and we’ll say what we think before you book.
Surfaces we seal
- Communal kitchens and washrooms
- Communal entrances and stairwells
- Window and door perimeters on blocks
- Balcony and threshold joints
- Shopfronts below residential blocks
- External wall and movement joints
Block-wide mastic in Nash
Nash is about 48 miles from central London. Within reach of London, blocks run by agents and associations are common around stations. The South East is one of the drier parts of the UK. Outside mastic still needs a dry joint and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first.
Churches, halls and community buildings such as Church of All Saints are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. For agents with blocks near Milton Keynes Central station (4.5 miles north-east of Nash), a block-wide mastic programme deals with frames, balconies and entrances in one go. Property owners at sites such as Greenway Business Park (to the south of Nash) can have mastic renewed between lettings.

How a job runs
In a busy building, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed before we move to the next. Jobs in and around smaller places like Nash are usually planned as a single visit, so photos and measurements up front really help. Then the right materials arrive with us.
- We inspect the joints, building by building, and record what has failed and why.
- You get a fixed quote, priced per building where that helps your budgeting.
- The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
- We remove the old mastic completely and clean the joint faces back.
- Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
- Finished joints are looked over and the 12-month guarantee confirmed.
Preparing the site
- Arrange parking or a loading space
- Point out any areas we must not close
- Share the asbestos register for older buildings
Getting a fixed quote
A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.

Questions we’re asked in Nash
We manage a building near Milton Keynes Central station. Can you help?
Yes. Managing agents, landlords, property factors and housing associations are who this service is for. We work to your notice and access arrangements.
Is Nash too small for you to travel to?
No. Small places get the same service as large ones. We work across Greater London and the South East. Good photos up front let us bring everything on the first visit.
Do you seal on top of existing sealant?
No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
What guarantee do you give on resealing?
Our workmanship carries a 12-month guarantee, backed by public liability insurance.
How long does a typical visit take?
It depends on the scope, though a typical visit normally takes one or more days per building, depending on the joint lengths and the access. Larger or phased jobs take longer, and we will give you a timescale with the quote.
Can you send RAMS and CSCS details before starting?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We are CHAS accredited and a Constructionline member.
Do you work for managing agents and housing associations?
Yes, that’s exactly who this service is for. We work through buildings in a planned order so you can plan around it.
Doing it in-house
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
Some joints are best left to specialists: for instance 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.
Cost factors for mastic joints
There’s no standard rate for sealant work, because every site is different. What we look at:
- Joint width, depth and condition
- Location, for remote and island sites
- Specialist products, such as fire-rated or hygienic sealants
- Phasing around occupants
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.
What we need to price the job
A few photographs plus some basic facts will normally do. Please tell us:
- Photos of the joints, close up and from further back
- Rough lengths or quantities, or drawings if you have them
- The site address and postcode
- How the joints are reached, and at what height
Quotes are fixed against the scope you send, so the cost is agreed before work starts. To start the process, ring 01277 525 020 or send photos by email.
