Our commercial sealant contractors service in AL3
A reseal stands or falls on the preparation underneath it. Old silicone gives new sealant nothing to grip, so every trace of it is removed and the faces are cleaned until they’re sound and dry, with no dust or grease left. Where the sealant maker specifies a primer for that substrate, it goes on before the new bead and the joint depth is controlled with backing rod. We work on floor and threshold joints, kitchen worktops and splashbacks and washrooms and tea points, and the failures we are asked to look at most are gaps behind commercial kitchen worktops and sinks and weathered facade sealant that no longer flexes.
Diagnose, treat, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off.
- You send photographs, drawings or a list of the joints and areas involved.
- Next comes a diagnosis and a fixed quote.
- Before anything is cut out, we agree access, timings and sequence.
- We strip the failed bead and prepare both faces of the joint.
- We fit backing to the right depth, prime where specified and lay the new bead.
- Each area is inspected, signed off and backed by our 12-month guarantee.

Shops, offices and hotels in AL3
From St Albans, Bernards Heath and Marshalswick outwards, AL3 has a broad spread of commercial premises: shops, offices, hotels, restaurants and units. Because we cover all of it, multi-site occupiers can bring every building under one quote, with colours matched site to site where the brand needs it.
The South East has large numbers of business parks and industrial estates, especially around the motorway corridors, and we cover AL3 along with the rest of the region.
Bernards Heath: For tenants and agents on sites such as Sandridge Gate Business Centre, which lies north-east of Bernards Heath, office fit-outs, reception joints and window perimeters are the usual sealant work. Shops and cafés around stations like St Albans station, 0.8 miles to the south of Bernards Heath, trade from early, so work is timed around them.
Honest limits
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Water from a services leak rather than a joint
- Leaking roofs, gutters or flat-roof membranes (those need a roofer)
- Faulty windows rather than failed perimeter sealant
Cost factors for sealant joints
The price varies from site to site. It mainly depends on:
- How much there is to seal
- Specialist products, such as fire-rated or hygienic sealants
- Phasing around occupants
- Site requirements such as inductions and permits
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we’ll explain how it’s made up.
Before you send an enquiry
There’s no need for a formal survey. These details are enough to start:
- Drawings or a marked-up plan, if available
- Photos of the joints, close up and from further back
- Your programme or deadline
- The asbestos register, for older buildings
We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, give us a call on 01277 525 020 or email a schedule or drawings.
Owners, agents and contractors
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
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 will confirm them with the quote.
Why it fails
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 all let go sooner than they should. BS 6213 gives guidance on choosing construction sealants, and many specifications refer to it.
Any of the following is a good reason to get the joints checked over:
- Untidy joints in a reception, shop floor or lobby
- A top-up bead over failed sealant, now lifting
- Movement joints packed with grit and debris
- Leaks that seem to come through a sealant line
Looking after the joints
A few simple habits keep the new joints working:
- Keep abrasive pads and scrapers off resealed joints
- Note dates and locations of sealant work for future planning
- Keep washroom and kitchen extraction working
- Check sealant as part of routine building inspections
New joints need their full cure time before they take water, cleaning or traffic. Cure time varies with the product, conditions and depth of the joint. Keeping signs or barriers up until then protects the finish.
Tenants and staff spot black or split sealant quickly. Replacing it on a planned cycle keeps complaints down.
AL3: questions and answers
Do you work in AL3?
Yes. We cover AL3 and the rest of Hertfordshire. To discuss a job, give us a call on 01277 525 020 or send photos by email.
Do you check for asbestos before removing sealant?
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 anything suspect is left until it has been tested.
Do you hold CHAS accreditation?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
How long do sealant joints last?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
How long does a job like this take?
The duration is planned around your programme and the access we’re given. You’ll have an expected duration with the quote.
Are your applicators CSCS-carded?
Yes. We use CSCS-carded applicators, as many construction sites ask for.
How do you choose the sealant?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
