Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
When to bring in a specialist
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.
How we handle commercial sealant contractors in Hersham
Sometimes a split bead is a symptom rather than the cause. Water at a window perimeter might be coming from the frame, the cill or the wall behind while a movement joint that keeps tearing may simply be too narrow for the job. Part of the job is telling you when the fix is something other than sealant, so budgets go where they’ll do some good. Site teams most often ask us about movement joints packed with grit and debris and smeared sealant across finishes from a rushed job, on movement joints in walls and floors, external facade joints and floor and threshold joints. For commercial sealant work in Hersham, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
If you look after more than one building near Hersham, the work can be planned as one programme, with one quote format and one point of contact.
Places like Hersham tend to have a handful of commercial buildings: a local shop, a pub or restaurant, a surgery, a school and the odd office or workshop. They’re not big jobs one by one, but their joints need the same preparation as anywhere.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

Commercial sealant contractors in Hersham: the local picture
Central London is about 16 miles from Hersham. The South East around the capital has large numbers of business parks, offices and retail centres, especially around the motorway corridors. Firms with branches across the South East can use one contractor for every site. A 2-mile radius around Hersham takes in a number of hotels. Hotel refurbishments are where a matched sealant colour earns its place: bathroom, bar and reception joints have to sit with the finishes; work is planned so the hotel keeps trading.
If you have premises on more than one site, say at Hersham Place Technology Park and Hersham Trading Estate, one contractor and one quote can cover both. For premises near Walton-On-Thames station, 0.6 miles to the north-west of Hersham, footfall is part of the plan: work is phased so shops and offices keep trading. On a business park such as Hersham Place Technology Park, which lies south-east of Hersham, sealant work tends to follow fit-outs: receptions, tea points, washrooms and frame perimeters.

Work for main contractors and building owners
Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.
As a CHAS accredited contractor and Constructionline member, we’re straightforward to vet for your supplier list. We’re fully insured, and our insurance certificate can go with the quote.
Why deal with it now?
Fixing joints complaint by complaint is a costly way to manage sealant. A planned programme groups work by building or area, cuts repeat visits and gives you a budget figure. We can help you prioritise, starting with the joints most likely to let water in. Over time, UV, weather and movement wear any sealant out. Renewing it in good time keeps the building weathertight.
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.

On site: what to expect
Working in a building that stays open takes some planning. We sign and contain the area we’re in, with routes through the building left open and work section by section so the rest of the building stays in use. For a job in Hersham, the main thing is a clear picture of the work, so send photographs of each area. A fixed quote follows.
- We begin with whatever information you have, whether that’s photographs, a drawing or a list of locations, or we arrange a site visit.
- Next comes a diagnosis and a fixed quote.
- Site hours, access windows and the order of areas are agreed before we start.
- The failed bead is removed and the joint faces cleaned until they’re sound and dry.
- The depth is set, primer is used where the maker calls for it, and the fresh bead is applied and tooled.
- Finished joints are checked with you and handed over with our 12-month guarantee.
Before we start on site

Advice
What sets the cost
We price every job individually. The main factors are:
- Phasing around occupants
- Quantities, in metres or numbers
- How much existing material needs removing
- Induction, permit and paperwork requirements
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 we will put a fixed figure on it.
Before you send an enquiry
For an accurate fixed quote, we need to understand the site. Useful things to include:
- Rough lengths or quantities, or drawings if you have them
- Clear photographs of the problem areas
- The site address and postcode
- Specification clauses that apply
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, ring 01277 525 020 or email a schedule or drawings.
What the job involves on each surface
Window and door perimeters
Inside, cracked sealant around frames and window boards is common. We use a paintable product where decorating follows and a silicone where it doesn’t, matched to the frame colour where colour matters.
Fire-rated seals where specified
Intumescent and other fire-rated sealants go in at service penetrations and linear gaps to the maker’s tested details, where they are specified. Fire-stopping design and sign-off sit with the designer, fire engineer or building control, and we install to the specification.
Questions we are asked in Hersham
Can you work at a site such as Hersham Place Technology Park, by Hersham?
Yes, sites like Hersham Place Technology Park are within our area, along with the rest of Hersham. To start, just give us a call on 01277 525 020 or use the quote form with the unit, the joints involved and your access times.
Is Hersham too small for you to travel to?
No. Places such as Hersham are covered as much as the big towns. Our area covers London and the South East counties. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Do you check for asbestos before removing sealant?
We check the asbestos register or survey before any old sealant is disturbed. The duty to manage asbestos sits with the dutyholder, and we don’t remove asbestos-containing materials.
Do you take on multi-site sealant work?
Yes. We take on runs of jobs across portfolios as well as single sites.
Is failed sealant stripped out, or sealed over?
Every scrap of failed sealant is removed before the new bead goes on. A bead laid on old silicone peels away, so it isn’t something we do.
Do you seal on top of existing sealant?
No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.
