Mastic sealing for commercial buildings in Shephall
We work for building owners, landlords with commercial or block portfolios, managing agents and housing associations. Many prefer a planned programme to one-off visits and we quote and schedule each building in turn. We work on communal entrances and stairwells, shopfronts below residential blocks and window and door perimeters on blocks, and the usual reasons a site gets in touch are draught complaints from residents or tenants and estate-wide sealant that is simply worn out. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Shephall, that means joint design, primers and backing rod as standard.
Places the size of Shephall normally have some housing association stock, small blocks and mixed-use buildings. The mastic around their frames and external joints ages like anywhere else.
We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

What affects the price in Shephall
To price the job, we consider:
- Distance, for remote addresses
- The product specified
- The size and state of each joint
- Removal of failed or old sealant
Pricing mastic joints depends on quantities, condition and access, and any specification that applies. Call for a quote.
What to include in your enquiry
We can often quote from photographs and a few details. Please tell us:
- Asbestos survey details if the building is older
- Drawings or a marked-up plan, if available
- Any specification or named product
- Whether the building will be occupied during the work
Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we will arrange a site visit if anything is unclear.
What we are called out for in Shephall
Much failed sealant was laid on dirty, dusty or damp surfaces. Where the faces weren’t cleaned or primed as specified it comes away from one face.
Any of the following is a good reason to get the joints checked over:
- Complaints coming in block by block
- Old repairs sealed over failed mastic
- Communal area joints that look neglected
- Draughts at frames across a block
With historic buildings such as Aston Bury (1.6 miles south-east of Shephall) in the wider area, owners of older properties around Shephall should expect mastic to need a product that suits old masonry.
What your quote should include
- The named product and why it was chosen
- The terms of the workmanship guarantee
- Whether primer will be used where the manufacturer specifies it
- How the existing material will be dealt with
Doing it in-house
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
For managing agents and facilities managers
FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.
Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
Common questions from Shephall clients
Can you work at a site such as Monkswood Retail Park, by Shephall?
Yes. Our area takes in Shephall and its surroundings, with estates and business parks such as Monkswood Retail Park included. To start, just speak to us on 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.
Is Shephall off your patch?
Not at all. Shephall is within our area. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.
Can you work to our specification?
Yes. We follow the specification, along with the manufacturer’s installation guidance.
Is any job too small?
Small jobs are welcome alongside larger packages. Send details for a fixed quote.
Does weather matter for sealant work?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
Do you work with property factors and landlords?
Yes, block and estate work is a core part of what we do. We work through buildings in a planned order with dates agreed in advance.
How long does a job like this take?
The duration is planned around your programme and the access we are given. You will have an expected duration with the quote.
Why act early in Shephall
Mixed repairs by different contractors leave a patchwork of products and colours. Resealing a whole building gives a consistent finish and one 12-month guarantee. A failed joint lets water into a building whatever its size. Catching it early means a reseal rather than repairs.
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.

Mastic sealing around Shephall: how the place shapes the job
The planned town of Stevenage is on Shephall’s doorstep. Phased building means whole estates with frames of a similar vintage, ideal for a planned mastic programme. Shephall sits in one of the drier corners of the country, the South East. External mastic still waits for dry faces and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first.
For owners of several units at places like Monkswood Retail Park, which lies west of Shephall, one programme can deal with frame and external mastic across the lot. Site managers at schools like Peartree Spring Primary School can fit frame mastic into the summer works.
