After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Several jobs near Shenfield can be grouped on one trip. Mention the building’s opening times and we will work within them.
- 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.

Mastic sealing for commercial buildings in Shenfield
Owners and agents typically inherit a building’s mastic rather than choose it, and it ages quietly: window perimeters, door frames, external joints and communal junctions all rely on it. When it hardens, splits or pulls away, water and draughts follow along with complaints. The enquiries we see most involve complaints coming in block by block and worn sealant at communal door frames, on external wall and movement joints, window and door perimeters on blocks and shopfronts below residential blocks. A specialist sealant contractor works differently from a general builder: on jobs in Shenfield, preparation and product choice get the time they need.
Owners with buildings around smaller places like Shenfield often group mastic work so one visit covers several properties. Send the addresses and photographs and we’ll quote for all of them together.
A 12-month guarantee applies to all our work in Essex. If an installation problem shows up, give us a call on 01277 525 020 or send photos by email and we will arrange a return visit.

Mastic sealing around Shenfield: points for this area
Two care or nursing homes sit less than 2 miles from Shenfield. Owners of care premises can bring window and door mastic into a phased programme planned around the home. Shenfield sits in one of the drier corners of the country, the South East. Even so, frame mastic only goes on in dry, workable conditions, and south- and west-facing elevations, which take the most sun and rain, often age first.
If you look after a block within reach of Shenfield station, which lies east of Shenfield, frame and balcony mastic can be renewed on one programme. With historic buildings such as Ingatestone Hall (to the north-east of Shenfield) in the wider area, owners of older properties around Shenfield should expect mastic to need a product that suits old masonry. Trustees of buildings like Church of St Mary the Virgin can bring frame and external mastic into a planned maintenance list.
Shenfield is about 1 mile north-east of Brentwood, in Essex. Commercial clients in Shenfield use us for work on mastic joints, as part of our coverage of Essex. Shenfield is one of 644 places we cover in Essex. For work in that direction, see our London page.

Nearby places we also cover include Brentwood (1 mile south-west), Hutton Mount (1 mile south-east), Hutton (2 miles east), Ingrave (2 miles south-east) and Mountnessing (2 miles north-east). A short drive away, we cover Chelmsford (10 miles north-east), Basildon (7 miles south-east), Harlow (13 miles north-west), Canvey Island (14 miles south-east), Billericay (4 miles east) and Rayleigh (13 miles east).
What’s near Shenfield
Locally, jobs take us to sites close to Sawyers Hall College, Hutton Country Park and Shenfield High School and the streets around them. Shenfield’s nearest station is Shenfield station, about 0.5 miles east. Other landmarks nearby include Brentwood Community Hospital (0.5 miles south). Green spaces nearby include Thorndon Park.
Should maintenance staff do it?
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong typically costs more in the end than doing them right.
Common questions from Shenfield clients
We manage a building near Shenfield 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 Shenfield too far out for you?
No. Small places get the same service as large ones. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Do you seal on top of existing sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
Do you supply RAMS and insurance details?
Let us know your requirements: tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We are CHAS accredited and a Constructionline member.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.
Can you plan resealing across several buildings?
Block-wide and estate programmes are common. You get a fixed quote per building or for the whole job.
Do you check for asbestos in old sealant?
Asbestos removal isn’t part of our work. Anything suspect is tested before we carry on, and the duty to manage asbestos sits with the dutyholder.
What the job involves on each surface
Planned maintenance
Mastic wears out like any building component; how fast comes down to movement, weather, UV and the product. Regular inspection is the best way to plan resealing.
Tenement and older buildings
Older buildings, including Scotland’s sandstone tenements, have their own joint details. We look at the substrate before choosing a sealant.
What sets the cost
We price every job individually. The main factors are:
- The product specified
- How much there is to seal
- Site requirements such as inductions and permits
- Whether the work must be split into stages
The specified product makes a difference, and so does the preparation. Access, phasing and site rules also count.
Details that help us quote
For an accurate fixed quote, we need to understand the site. Useful things to include:
- Your programme or deadline
- Any specification or named product
- The asbestos register, for older buildings
- The postcode of the building
Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we’ll fill any gaps with a visit.
Keeping the joints sound
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:
- Start inspections with the most exposed faces
- Have the asbestos survey to hand for older buildings
- Avoid piecemeal callouts where you can
- Reduce knocks to communal area joints
Keep records of when each building was resealed. It helps plan the next round and shows what was done.
Joints on a building age together, so it pays to look at the whole elevation. Doing them together saves going back again and again.
Why act early in Shenfield
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. In a smaller place such as Shenfield, getting a contractor back for a second visit takes time, so we’d suggest renewing all the joints that are going, not just the worst.
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.
