Mastic sealing in Benington, done properly
Blocks are lived in, so access and disruption have to be thought through. The sequence, the areas and the dates are settled with you, giving you what you need to notify residents. Communal entrances and stairs stay usable while we work. Most enquiries involve complaints coming in block by block and failed external movement joints, on communal entrances and stairwells, shopfronts below residential blocks and balcony and threshold joints. Facilities teams, main contractors and managing agents in Benington tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Around smaller places like Benington, older walls fitted with newer windows are a familiar sight. Perimeter mastic there has to grip an uneven face and suit the building’s character.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

When to bring in a specialist
A short, simple internal joint is often within reach of a maintenance team. 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.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
Questions we’re asked in Benington
Is Benington too small for you to travel to?
Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.
Do you cover business parks and estates near Benington, such as Astonbury Farm & Business Park?
Yes. Our area takes in Benington and its surroundings, with estates and business parks such as Astonbury Farm & Business Park included. Send details of the unit and the work through our quote form for a quick quote.
Can you plan resealing across several buildings?
We can. Each building is inspected, quoted and scheduled in turn, and the programme can start with the worst.
What’s the quickest route to a quote?
It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photos and a postcode.
Do you work for managing agents and housing associations?
Yes, block and estate work is a core part of what we do. Buildings are scheduled in turn with dates agreed in advance.
How long does a typical visit take?
That varies with the scale of the job, though a typical visit normally takes a few days for most blocks, with larger programmes scheduled building by building. For bigger or phased jobs, we’ll set out a timescale with the quote.
Is it fine to apply new sealant on top of old?
No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
What we can’t put right
Being straight saves everyone time. New sealant won’t cure:
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Frames that are rotten, warped or broken
- Broken glass or failed sealed units
If you are not sure, just call the office on 01277 525 020 or use the quote form and we will give you a straight answer.

Mastic sealing around Benington: points for this area
Benington lies roughly 27 miles out from central London. Managed blocks of flats are a big part of commuter-belt property. Rainfall across the South East, Benington included, is lower than in many parts of the UK. Outside work still depends on dry joints, and south- and west-facing elevations, which take the most sun and rain, often age first.
Property owners at sites such as Astonbury Farm & Business Park, 1.9 miles south-west of Benington, can have mastic renewed between lettings. Trustees of buildings like Parish Church of St Peter can bring frame and external mastic into a planned maintenance list.
Benington is about 3 miles east of Stevenage, in Hertfordshire. Anywhere in SG2, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Benington is one of 371 places we cover in Hertfordshire. There’s a separate page for London, about 27 miles away.
Work on mastic joints is covered throughout SG2, for business premises of every kind. For a building on Blacksmiths Hill, Town Lane and Three Stiles or nearby, send details and we’ll quote for mastic joints. Just outside Benington, we also work in Aston (2 miles west), Hook's Cross (2 miles south-west), Bragbury End (3 miles south-west), Watton at Stone (3 miles south) and Shephall (3 miles west).

What happens if it’s left?
Looking at mastic during planned maintenance costs little. Waiting until leaks appear means working under pressure with less control over timing. One visit to deal with every failing joint makes more sense than several trips to a place like Benington, rather than one at a time. Send photos of each area and we’ll quote for the lot.
There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote.

Do you need mastic sealing in Benington?
We often find joints filled solid with no backing rod so the mastic is bonded on three sides. It can’t stretch properly and splits as the building moves.
Look out for the following:
- Movement joints with sealant missing
- Draught complaints from residents or tenants
- Estate-wide sealant that is simply worn out
- Leaks at window and door perimeters
For a school such as Benington Church of England Primary School, perimeter mastic on windows and doors is a holiday job.

Surface by surface
Commercial and mixed-use buildings
Tenants in commercial buildings need to keep trading, so we plan around them.
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.
