On site: what to expect
Site rules come first: signing in, inductions and any permit to work. With the paperwork done, the joints are worked through in the order agreed with your site contact. If you have more than one building in Newhaven, they can often be done on the same visit. Tell us when the building is open and we’ll plan to suit.
- First, details come to us: photos, drawings or a schedule of the areas, and a site visit is booked where it helps.
- We work out why the joints have failed and fix a quote for the agreed scope.
- Site hours, access windows and the order of areas are agreed before we start.
- We strip the failed bead and prepare both faces of the joint.
- Backing and primer go in where needed, then the chosen sealant is applied and tooled.
- Finished joints are checked with you and handed over with our 12-month guarantee.
Preparing the site
- Let us know about inductions and permits
- Make sure the joints can be reached

About our commercial sealant contractors in Newhaven
Sealant joints are easy to overlook until one lets water in, and on a working site that usually surfaces as a leak, a stain or a complaint from occupiers. We are commercial sealant applicators for FMs, managing agents, landlords and contractors with sites in Newhaven. We find out why the sealant joints failed, take them out and seal again using a sealant that suits the joint. The enquiries we see most involve movement joints packed with grit and debris and frame sealant that has cracked, shrunk or pulled away, across floor and threshold joints, washrooms and tea points and external facade joints. A single leaking joint is often how a building in Newhaven first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Quotes for commercial sealant in Newhaven can come from photos and a joint schedule, or from a walk-round, with the scope listed so everyone knows what’s included.
In towns of Newhaven’s size, shops and offices often occupy older buildings with later extensions and new shopfronts. Where old meets new there are junctions between brick, render, timber and aluminium, and each needs the right sealant.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Common questions from Newhaven clients
Does the sea air around Newhaven change the choice of sealant?
It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.
Must a hotel around Newhaven close while you work?
Almost never. The work is phased so most rooms stay available. The plan is built around your bookings.
Do you work in Newhaven?
Yes. Newhaven is in our area, within our coverage of Greater London, South East England and Scotland. To discuss a job, give us a call on 01277 525 020 or email the details over.
How long do sealant joints last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
Can you follow the specification on our project?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.
How do you choose the sealant?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
What about asbestos in old mastic?
In buildings from before 2000 in particular, some old mastics and sealants may contain asbestos. We ask to see the asbestos register or survey before disturbing old sealant, and if something is suspected, work stops until it’s tested.
Common problems we fix in Newhaven
Plenty of failed joints were never sealed with the right product. Painters’ acrylic in a moving joint, vinegar-smelling silicone on metal or natural stone, or a high-modulus product where a low-modulus one was needed. BS 6213 gives guidance on choosing construction sealants, and many specifications refer to it.
It’s worth sending us details if you spot any of the following:
- Greasy, split joints in a kitchen or tea point
- Leaks that seem to come through a sealant line
- Untidy joints in a reception, shop floor or lobby
- Window and door perimeter joints that have cracked open
For premises near Newhaven Town station (under half a mile east of Newhaven), footfall is part of the plan: work is phased so shops and offices keep trading.
What your quote should include
- Proof of insurance
- Are they CHAS accredited or on Constructionline?
- How they handle RAMS and site documents
- How long is the guarantee, and what does it include?
Commercial premises in Newhaven
The sea is no more than about 1 mile from Newhaven. Buildings near the sea put their external joints through more driven rain, with salt air nearer the beach. A matched colour is only half the brief on an exposed frontage. A number of hotels sit less than 2 miles from Newhaven. A hotel refurbishment is full of joints that guests will see, and a matched colour keeps them discreet.
If you have premises on more than one site, say at Newhaven Industrial Park and Meridian Industrial Estate, one contractor and one quote can cover both. Refits at hotels like The Ship Hotel, less than half a mile north of Newhaven, bring joints at vanity tops, bars and reception desks that guests see every day.

- Whether the work must be split into stages
- Any access equipment needed
- The total length or number of joints
- Induction, permit and paperwork requirements
A quote for sealant joints depends on quantities, condition and access. Call for a quote.
Sending details for a quote
However big the job, these details speed things up:
- Rough lengths or quantities, or drawings if you have them
- Whether an asbestos survey exists
- Access details, including height
- Where the site is, with the postcode
Send us photographs, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.
Why it’s worth doing now in Newhaven
It can be tempting to hold sealant work back until the next refurbishment. For internal joints that are only cosmetic, that can make sense, but external and wet-area joints that already leak shouldn’t wait. Splitting the scope into now and later is often the sensible compromise. For businesses and landlords in Newhaven, a tidy, sound joint also matters for appearance. Renewing it keeps the building looking cared for.
There’s no price list, because the scope varies so much from one building to the next. Call for a quote.

When it isn’t the sealant
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:
- Leaks from pipework, wastes or valves (that’s plumbing)
- Old mastic that tests positive for asbestos
- Broken glass or blown double-glazed units
Not sure which it is? You can speak to us on 01277 525 020 or email us and we’ll tell you honestly before you book.
Surfaces we seal
- Movement joints in walls and floors
- Floor and threshold joints
- External facade joints
- Window and door perimeters
- Washrooms and tea points
- Kitchen worktops and splashbacks
Work for main contractors and building owners
FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.
We work for building owners and managing agents on everything from one building to a spread of sites. Several sites can go on one quote, so there’s one set of paperwork to deal with.
