Commercial sealant contractors in Wallington
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. We work on washrooms and tea points, floor and threshold joints and movement joints in walls and floors, and the failures we’re asked to look at most are frame mastic that has hardened and come away from the wall and layers of sealant, all of them failing. For commercial sealant work in Wallington, you deal with one contact from quote to sign-off, whether it’s one building or several.
We price commercial jobs in Wallington from photographs, drawings or a site visit, with the scope listed so everyone knows what’s included.
A job in a smaller place like Wallington is usually a single building. We plan the visit so everything on the list is done in one go, with the right products and colours on hand.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

What sets the cost
Before we quote, we look at:
- Removal of failed or old sealant
- The size and state of each joint
- The site’s rules and procedures
- Distance, for remote addresses
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote and we’ll explain how it’s made up.
What to include in your enquiry
The more we know, the firmer the quote. When you get in touch, include:
- Specification clauses that apply
- Where the site is, with the postcode
- Rough lengths or quantities, or drawings if you have them
- Asbestos survey details if the building is older
Let us know the site, the scope and your timescale, and a fixed quote will follow. To get it moving, give us a call on 01277 525 020 or email a schedule or drawings.
Should maintenance staff do it?
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
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.
Keeping the joints sound
Keep the joints in good shape with a few simple steps:
- Check sealant as part of routine building inspections
- Make sure contractors see the asbestos survey before cutting out old mastic
- Keep washroom and kitchen extraction working
- Keep a record of which joints were resealed and when
In washrooms and kitchens, extraction makes a real difference to sealant life. Extraction that isn’t working keeps the joints wet, and mould follows damp. It’s worth having fans checked while the sealant is fresh.
In kitchens and washrooms, a failed joint is a cleaning problem as well as a leak risk. Cleanability is something environmental health officers pay attention to, so sound, smooth joints matter.

What else we do in Wallington
Leave it or put it right?
A cheaper quote sometimes means the old bead stays in. New sealant laid on old silicone has nothing to bond to, so it peels. Every quote we give includes full removal and preparation. Converted and older buildings near places like Wallington tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.
What you get with us
- Work to your specification and the manufacturer’s guidance
- Failed material removed, not covered up
- Sealing commercial buildings since 2005
- Matching to RAL references, product permitting

How a job runs
When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, and the work usually takes a few hours to several days on most single sites, depending on joint lengths and access. Jobs in and around smaller places like Wallington are typically planned as a single visit, so photos and measurements up front really help. Then the right materials arrive with us.
- We start with the evidence: photographs, drawings or a look on site.
- You get a fixed quote covering removal, preparation and the new sealant.
- Sequence, access and working times are settled before the first joint is touched.
- Each joint is stripped, cleaned back to sound faces and primed where the maker specifies.
- Depth is set with backing, then the sealant is applied, tooled and the area tidied.
- Completed areas are signed off with you under our 12-month guarantee.
Getting the site ready
- Have the specification and drawings to hand
- Make sure the joints can be reached
- Let building users know which areas are affected

What sealant work can’t fix
A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is one of these:
- Walls or slabs moving more than any sealant can take
- Leaks from pipework, wastes or valves (that’s plumbing)
- Roof leaks that only look like a joint problem
If you are not sure, just give us a call on 01277 525 020 or email a schedule or drawings and we will give you a straight answer.
Surfaces we seal
- Window and door perimeters
- Washrooms and tea points
- Floor and threshold joints
- External facade joints
- Movement joints in walls and floors
- Kitchen worktops and splashbacks

Business parks and retail centres are common around the capital’s motorway corridors. If you have premises across the region, one contractor can cover them all.
Whatever the building in Wallington, commercial sealant work starts with cutting out the failed bead and cleaning the joint back to sound material.
