How we handle construction mastic in Havering's Grove
On refurbishments, the mastic package usually includes cutting out old sealant as well as sealing new work. Old beads come out completely, as fresh silicone can’t grip old. New and existing joints then get the same preparation. We work on cladding and panel joints, brick and block movement joints and sanitary and kitchen joints, and the failures we are asked to look at most are frame gaps too wide for sealant alone and bath and shower joints scraped during the final clean. Whether you call it commercial sealant work, mastic application or joint sealing, in Havering's Grove it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
For a site near Havering's Grove, the mastic visit is planned so the right sealants, primers and backing rod are on hand, timed to the stage the job has reached. Drawings, photographs and the programme let us give a fixed quote.
We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Common problems we fix in Havering's Grove
Swapping the specified sealant for a cheaper general-purpose product is a common cause of failure. A general-purpose silicone on a facade or a caulk in a wet area won’t perform like the specified product. We use what’s specified, and any substitute goes to you for acceptance.
These are often picked up first by site or facilities staff:
- New external sealant already peeling away
- Mastic snags holding up handover
- Missed perimeter joints on a new elevation
- Old sealant on a refurbishment that needs stripping before new work
School extensions, at buildings such as The Billericay School, normally run to the summer holidays, mastic included.
Questions to ask before you book
- How they’ll work around occupants
- What level of public liability insurance do they hold?
- Whether old or failed sealant will be cut out, not overlaid
- Their approach to joint depth and backing
Contractors’ notes for Havering's Grove
The South East is one of the drier parts of the UK. Winter mornings still bring frost and condensation on frames and panels, so external mastic is timed for workable conditions and agreed with the site manager. At about 22 miles from central London, Havering's Grove is within reach of the capital. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, which keeps mastic packages in demand.
For a contractor working at a hospital such as Brentwood Community Hospital, 2.9 miles west of Havering's Grove, perimeter and facade sealing is planned around patients and deliveries. Historic houses such as Ingatestone Hall (2.4 miles north of Havering's Grove) are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.

What affects the price in Havering's Grove
We price every job individually. The main factors are:
- The total length or number of joints
- How much existing material needs removing
- The site’s rules and procedures
- The size and state of each joint
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we’ll explain how it’s made up.
Details that help us quote
For an accurate fixed quote, we need to understand the site. Send us:
- Any dates the work must fit around
- The postcode of the building
- Whether an asbestos survey exists
- The product your specification calls for
Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.
FAQs: Havering's Grove
Can you take on a job at a hospital such as Brentwood Community Hospital?
Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.
Can the mastic package for our job in Havering's Grove follow the site programme?
Yes. Send the programme and drawings, and we will plan the mastic to suit the stages. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
What about RAMS and site documents?
Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.
How long will the new sealant last?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
Can you work to our specification?
We use the product the specification names. If we think an alternative would suit better, we put it to you first.
Is the mastic package guaranteed?
The work is guaranteed for 12 months. Keeping other trades off finished joints prevents most problems.
How do we ask for a quote?
There are four steps: send details, get a quote, we seal, guaranteed. The first step only needs photos and a postcode.
After the work
A few simple habits keep the new joints working:
- Check frame gaps are within the sealant’s range before sealing
- Bring the mastic contractor in after the last trades are through
- Brief following trades on areas that have been sealed
- Keep scrapers and abrasive pads off new beads
Brief the sparkle clean so they don’t scrape the new joints. Scrapers used on frames and worktops can nick or lift a new bead.
Frames with gaps too wide for sealant need sorting before the mastic goes on. Sealant stretched over an oversized gap won’t last, so the installer needs to correct it first. We flag them as soon as we see them.
What we can’t put right
Honesty saves time and money. New sealant won’t cure:
- Approving fire stopping as compliant
- Designing joint widths or choosing the specification (that sits with the designer)
- Damage to finishes by other trades after we’ve sealed
Not sure which it is? You can phone 01277 525 020 or email the details over and we’ll tell you honestly before you book.

Why act early in Havering's Grove
Sealing over damaged or contaminated new joints might save a day, but it rarely lasts. Sealant can’t grip a contaminated or existing bead. Damaged joints are removed and resealed from clean faces. Converted and older buildings near places like Havering's Grove tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.
