What happens if it’s left?
When a package runs over budget, downgrading the product is a common first thought. The saving is small next to the cost of callbacks and defects. Where an alternative is genuinely suitable, we’ll say so. Around Hamstreet, it’s better to renew all the failing joints at once. Send photos of each area and we will quote for the lot.
What a job costs comes down to the quantity of joints, how much old material needs removing and how the joints are reached. Call for a quote when you’re ready.

How we handle construction mastic in Hamstreet
On refurbishments, the mastic package normally 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. If you are dealing with early adhesion failures on new external joints and bath and shower joints scraped during the final clean, we can put it right, whatever the surface. A specialist sealant contractor works differently from a general builder: on jobs in Hamstreet, preparation and product choice get the time they need.
Sites around smaller places like Hamstreet can be a fair drive from suppliers, so we come with everything the package needs. Drawings, photos and the programme let us give a fixed quote.
Our workmanship is guaranteed for 12 months, in Hamstreet as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

General trades versus a specialist
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Construction mastic around Hamstreet: how the place shapes the job
The South East is one of the drier parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so the external programme keeps a little slack. At about 51 miles from central London, Hamstreet is within reach of the capital. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and main contractors there need mastic that keeps to the programme.
For a contractor working at a hospital such as William Harvey Hospital, 5.8 miles north-east of Hamstreet, perimeter and facade sealing is planned around patients and deliveries. For contractors at a school such as Hamstreet Primary Academy, sealing has to be finished before term starts.
Hamstreet is about 5 miles south of Ashford, in Kent. We cover Hamstreet and the rest of Kent, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Across Kent, 931 places are covered, including Hamstreet. Brighton is covered too, around 46 miles from Hamstreet.

Signs you need construction mastic in Hamstreet
Frames installed with uneven gaps make perimeter sealing harder. Every product has limits on how wide a joint it can bridge. We flag them early rather than filling them with sealant that won’t last.
Typical triggers for a call:
- External joints sealed in damp or cold conditions that are now failing
- Missed perimeter joints on a new elevation
- Frame gaps too wide for sealant alone
- Caulk cracking where joints are moving more than expected
Units on estates such as Meadow View Business Park (to the east of Hamstreet) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.
Questions to ask before you book
- Do they follow the manufacturer’s priming guidance?
- Their plan for phasing and protecting the area
- Will CSCS-carded applicators be on site?
- How they handle RAMS and site documents
Questions we’re asked in Hamstreet
Is Hamstreet too small for you to travel to?
No. Places such as Hamstreet are covered as much as the big towns. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
Will you take on work at estates like Meadow View Business Park, close to Hamstreet?
Yes. Our area takes in Hamstreet and its surroundings, with estates and business parks such as Meadow View Business Park included. A few photos and the unit address let us price the work.
How long does a typical visit take?
We plan the time on site around your programme and access. You will have an expected duration with the quote.
Will you quote for a small job?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
How do I request a quote?
The quote form is the simplest route, though you can also call the office on 01277 525 020 or use the quote form. Include photos or drawings if you have them.
Can weather delay the job?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
Can you send site paperwork?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.
From enquiry to sign-off
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, and the work usually takes anything from a day of snagging to several weeks of plot-by-plot sealing on a phased scheme. Smaller jobs around Hamstreet can be grouped with others nearby, which keeps travel down. You’ll have a fixed quote before work starts.
- We price from the drawings, specification and programme you send.
- You receive a fixed quote listing scope, products and phasing.
- You tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we confirm it with the quote.
- Areas are sealed plot by plot or floor by floor as the trades hand them over.
- Each joint is prepared, backed to depth and sealed in the product the specification names.
- We close out snagging and hand over with a 12-month guarantee.
Getting the site ready
- Arrange parking or a loading space
- Flag any permit to work we’ll need
- Move anything stored against the joints
Request a quote
Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.
Advice
Surface by surface
Fire-rated sealant where specified
Not every penetration suits a sealant. Other products are used for some services and gaps so we will flag where the detail needs something different. Record requirements are agreed with the quote.
External facade and movement joints
Brickwork, blockwork and panel movement joints need a sealant with the right movement capability. We set the depth with backing rod to avoid three-sided adhesion.
What we can’t put right
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Glazing units that are cracked or misted
- Joints damaged after sign-off by following trades
- Specifying the product where the designer hasn’t
If in doubt, call 01277 525 020 or email the details over and we’ll say what we think.
Joints and surfaces we work on
- Floor and skirting junctions
