Honest limits
We check first that sealant really is the fix. It isn’t the answer for:
- Misted, cracked or failed glazing units (a glazier’s job)
- Water from a services leak rather than a joint
- Walls or slabs moving more than any sealant can take
If you are not sure, just speak to us on 01277 525 020 or email the details over and we’ll give you a straight answer before you book.
What we seal

How we handle commercial sealant contractors in Ham
Having a single contact for all your sites makes sealant far simpler to manage. We take on one-off reseals, runs of jobs across a portfolio and planned maintenance programmes: send details, get a fixed quote, we seal, and a 12-month guarantee once it’s signed off. For sites in Ham, the quickest start is to call the office on 01277 525 020 or email us with a list of addresses. Most enquiries involve wall and floor joints that have lost their seal and sanitary sealant that has gone black and patchy, on washrooms and tea points, kitchen worktops and splashbacks and window and door perimeters. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Ham is the same: the right product in a properly prepared joint.
Multi-site clients with buildings in and around Ham can put several sites on one programme, so standards and paperwork match across every site.
In London, most commercial sealant work happens in buildings that stay open: offices with staff at their desks, shops trading below flats and receptions that can’t be roped off for long. Work is split into zones agreed with the building or facilities manager, so the premises keep working around us.
We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Shops, offices and hotels in and around Ham
Less than 3 miles from Ham there are at least three named estates and business parks. Units on sites like these change tenants and get refitted, and each refit leaves joints to seal; brand colours often come into it. Most London commercial buildings run contractors through a reception, a permit system and booked goods-lift slots. We plan around them and agree phasing so tenants and customers aren’t disrupted.
A business with units at St. George's Industrial Estate and Newmans Shipyard & Business Park needn’t use two contractors for its sealant. In hotels such as Alexander Pope Hotel, 1 mile to the west of Ham, refurbishments typically mean bathroom, bar and reception joints where a matched sealant colour has to sit with the finishes.
Ham is about 1 mile south-east of Twickenham, in Greater London. Businesses, contractors and managing agents in Ham can call on us for sealant joints, as part of our coverage of Greater London.

How the job changes by surface
Shop fronts and retail fit-outs
Most shops can’t close for a reseal. Tell us your trading hours and access windows and we will plan around them.
Fire-rated seals where specified
Fire-rated sealant is only one type of fire-stopping product. Collars, wraps, batts and boards are specified for other services and gaps, so we will flag it if the detail needs a different product.
Your questions answered
Can you work in a London building with booked loading and goods-lift slots?
Yes, most London buildings have access rules of some kind, and we plan around them. Share the building’s contractor rules and we’ll work to them. We allow for the ULEZ, which covers every borough
Will our hotel in Ham need to close for the work?
Almost never. The work is phased so most rooms stay available. Tell us your quiet periods and access windows and we will plan around them.
Is it fine to apply new sealant on top of old?
No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.
What guarantee do you give on resealing?
The work is guaranteed for 12 months. Should a joint we sealed give trouble during those 12 months, let us know and we will look at it.
How many days will you need on site?
We plan the time on site around your programme and access. We’ll give you an estimate of time on site when we quote.
Is Ham in your area?
Yes. Ham falls within our area, and you can ring 01277 525 020 or email us to get started.
When is resealing likely to be due?
Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
When to bring in a specialist
Some joints are best left to specialists: for instance 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.
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 where general trades tend to cut corners.
Cost factors for sealant joints
A fixed quote reflects the actual work. It allows for:
- How accessible the joints are
- Whether old sealant has to be cut out first
- Site requirements such as inductions and permits
- Specialist products, such as fire-rated or hygienic sealants
The product called for affects the cost, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site rules also count.
Before you send an enquiry
Whether it’s one area or a whole building, these details speed things up:
- The postcode of the building
- When you need the work done
- Photos of the joints, close up and from further back
- Drawings or a marked-up plan, if available
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.
Common problems we fix in Ham
Plenty of failed joints were never sealed with the right product. Decorators’ caulk on a joint that moves, acetoxy silicone on stone or metal, or a stiff sealant on a facade will all fail early. BS 6213 gives guidance on choosing construction sealants.
These are often picked up first by site or facilities staff:
- Weathered facade sealant that no longer flexes
- Frame sealant that has cracked, shrunk or pulled away
- Water staining near frames, panels or ceilings
- Shrunken sealant along kitchen worktops and splashbacks
Units at places like Bentall Centre (to the south of Ham) are refitted as brands change, and the joints have to suit each new scheme.
Before you book anyone
- Will RAMS and insurance details be available?
- How the joint faces will be prepared and primed
- The terms of the workmanship guarantee
- Their public liability cover
On site: what to expect
The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. For a job in Ham, access comes first: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Send the building rules and access times with your enquiry.
- Send details through our quote form, or ask for a site visit.
- The cause is diagnosed and the scope priced as a fixed quote.
- Work is phased around your occupiers where areas need to stay in use.
- Every failed bead is removed rather than covered.
- Each joint gets a suitable sealant, laid to depth and tooled.
- A final walk-round, then the 12-month guarantee applies.
Preparing the site
- Tell us which areas need to stay in use
- Point out parking and an unloading spot
- Send asbestos survey details if the building is pre-2000
