Mastic sealing in Benslow
Owners and agents normally inherit a building’s mastic rather than choose it, and it ages quietly: it sits round windows and doors, along external joints and through communal areas. Once it cracks, hardens or comes away, draughts and water find a way in, and occupiers start reporting it. We work on shopfronts below residential blocks, window and door perimeters on blocks and communal entrances and stairwells, and the usual reasons a site gets in touch are draught complaints from residents or tenants and mastic failing across several blocks on an estate. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Benslow it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
In a smaller place such as Benslow, landlords and agents tend to look after small blocks, flats over shops, sheltered housing and commercial units. The mastic around their frames and external joints ages like anywhere else.
We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

At about 32 miles from central London, Benslow is within reach of the capital. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres.

Honest limits
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:
- Failed window or door frames, which need a window contractor
- Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
- Masonry that has broken away beside the joint
Not sure which it is? You can call 01277 525 020 or email drawings and photos and we’ll tell you honestly.
Surfaces we seal
- Shopfronts below residential blocks

Different surfaces, different methods
Window and door perimeters on blocks
We typically work through a block’s windows in a planned order. Access is agreed with you before the quote is fixed.
Communal areas
Joints at low level in communal areas take knocks from bins, bikes and buggies, so they often need renewing sooner.
Do you need mastic sealing in Benslow?
UV and rain age external sealant. The surface chalks, the body stiffens and cracks appear most of all on the sunniest and most exposed elevations.
These are often picked up first by site or facilities staff:
- Failed external movement joints
- Worn sealant at communal door frames
- Occupiers reporting cold air round windows
- The same joint failures repeated across a portfolio
For agents with blocks near Hitchin station (under half a mile north of Benslow), a block-wide mastic programme deals with frames, balconies and entrances in one go.

FAQs: Benslow
Is Benslow too small for you to travel to?
No. Small places get the same service as large ones. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.
Can work in a care setting near Benslow go ahead while residents are there?
Yes. We work around residents’ routines, a room or two at a time. Noise and disruption are kept to a minimum.
Who decides which product is used?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
What paperwork can you provide?
We are CHAS accredited, a Constructionline member and carry public liability insurance. For specific documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
Do you do block-wide mastic programmes?
Block-wide and estate programmes are common. The quote can be split however suits your budgeting.
Do you check for asbestos in old sealant?
Asbestos removal isn’t part of our work. If old sealant is suspected, work stops until it’s tested, and the duty to manage asbestos sits with the dutyholder.
What about access for upper-floor joints?
We talk through access for each building when we quote. Tell us the number of storeys and whether scaffold or other access is planned and we will confirm the approach in the quote.
How a job runs
On arrival, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, with the work itself usually taking a few days for most blocks, with larger programmes scheduled building by building. If neighbouring businesses or buildings around Benslow need work too, visits can be combined. Tell us your site hours and we’ll plan around them.
- First comes a look at the joints and, for older buildings, the asbestos records.
- The products and programme are set out in a fixed quote.
- Failed mastic is removed completely.
- Joint faces are cleaned, backed and resealed.
- Buildings are completed in turn.
Before we start on site
- Clear stock, furniture or equipment away from the joints
- Tell staff and tenants when we’ll be in
- Send asbestos survey details if the building is pre-2000
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.

What else we do in Benslow
Why it’s worth doing now in Benslow
Draughts round window perimeters cost occupiers comfort and the windows typically get the blame. Resealing the perimeters is often the simpler fix where the frames themselves are sound. Sealant hardens, cracks and loses grip with age, UV and movement. Renewing it in good time keeps the building weathertight.
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.
