Looking after the joints
After handover, these steps help:
- Don’t let cleaning or traffic back on before the cure time is up
- Make sure contractors see the asbestos survey before cutting out old mastic
- Keep a record of which joints were resealed and when
- Have extract fans checked so wet areas dry out
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, and we confirm it when each area is handed back. Leaving the area closed until then keeps the bead neat.
Occupiers often notice failing sealant before the facilities team does, and in a hotel, office or shop it makes the whole space look neglected. Replacing it on a planned cycle keeps complaints down.
About our commercial sealant contractors in St Albans
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’re commercial sealant applicators for FMs, managing agents, landlords and contractors. Our job is to diagnose the failure, remove the old bead and seal again using a product chosen for the movement and exposure. If you have expansion joints with the sealant torn out and untidy joints in a reception, shop floor or lobby, we can help. Most enquiries from St Albans start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
If you look after more than one building near St Albans, the work can be planned as one programme, with one quote format and one point of contact.
Shop units in larger centres such as St Albans change hands and get refitted often, and each refit leaves joints at counters, shopfronts, floor edges and wall panels. Where the joint is on show, the sealant colour matters as much as the bead itself.
Work we carry out comes with a 12-month guarantee. Should something we installed fail, ring 01277 525 020 or send details through our quote form and we will come back to it.

When it isn’t the sealant
Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be any of the following:
- Broken glass or blown double-glazed units
- Suspect materials that need testing and specialist removal
- Walls or slabs moving more than any sealant can take
If in doubt, give us a call on 01277 525 020 or email us and we will say what we think.
Surfaces we seal
- Washrooms and tea points
- Floor and threshold joints
- Window and door perimeters
- Kitchen worktops and splashbacks
- External facade joints
- Movement joints in walls and floors
From enquiry to sign-off
We follow your site rules from the start: signing in, inductions and any permit to work. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. Town-centre jobs in St Albans can mean limited parking and loading, whereas edge-of-town units normally have yard space. Let us know what’s there when you send details.
- You send photos, drawings or a list of the joints and areas involved.
- The failure is diagnosed and a fixed quote issued for the work agreed.
- We plan around your site hours and access windows, phasing the work where areas have to stay in use.
- Failed sealant is cut out and each joint cleaned back to sound, dry faces.
- The depth is set, primer is used where the maker calls for it, and the fresh bead is applied and tooled.
- Each area is inspected, signed off and backed by our 12-month guarantee.
Getting the site ready
- Move anything stored against the joints
- Point out any areas we must not close
- For older buildings, check the asbestos register before work

Advice
St Albans: questions and answers
Does a hotel in St Albans need to shut while its sealant is renewed?
Rarely, if ever. We take a few rooms out at a time. Housekeeping and our team agree each day’s rooms.
Can you match sealant colours for premises in St Albans?
Yes, sealants come in a wide range of standard colours, and matching to RAL references, cladding, stone or frames is a common request. Available colours for the product are confirmed with the quote.
Can you take on work for an FM or managing agent?
Yes. A large share of our work comes through facilities managers, managing agents and landlords as well as contractors. Tell us how you issue work and we will fit in.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
How long do sealant joints last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
Is St Albans in your area?
Yes. We cover St Albans. For a quote, speak to us on 01277 525 020 or email us.
How long does a job like this take?
That varies with the scale of the job, though a typical visit typically takes anything from part of a day on a short run of joints to several weeks on a large phased package. For bigger or phased jobs, we’ll set out a timescale with the quote.
What sets the cost
Sealant work doesn’t have a standard rate, because every site is different. What we look at:
- Specialist products, such as fire-rated or hygienic sealants
- Whether old sealant has to be cut out first
- Joint width, depth and condition
- The total length or number of joints
There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we will price your job on its own details.
Before you send an enquiry
We can often quote from photographs and a few details. It helps to include:
- Rough lengths or quantities, or drawings if you have them
- When you need the work done
- The site address and postcode
- The type of building and who uses it
To get a fixed quote, ring 01277 525 020 or email a schedule or drawings. Our quote form is another easy route.
Commercial sealant contractors in St Albans: the local picture
Two care or nursing homes sit less than 2 miles from St Albans. Kitchens and communal rooms in care settings are cleaned constantly, so their joints need to be smooth and sound, often in colours that suit the décor. The area within 2 miles of St Albans holds plenty of hotels. Refits in hotels bring joints at vanity tops, bar counters and reception desks where the colour has to suit the scheme; work is planned so the hotel keeps trading.
Units at places like Village Arcade St Albans, 0.5 miles to the west of St Albans, are refitted as brands change, and the joints have to suit each new scheme. Trade counters and showrooms on estates such as Verulam Industrial Estate (0.6 miles south of St Albans) need neat joints where customers see them. Occupiers with premises at both Verulam Industrial Estate and Sandridge Gate Business Centre could have the sealant at each handled under one quote.
St Albans is about 20 miles north-west of London, in Hertfordshire. We cover St Albans, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. We work across 371 places in Hertfordshire. We also cover London, around 20 miles from St Albans.

Why deal with it now?
Some low prices are low because nothing gets cut out. New sealant laid on old silicone has nothing to bond to, so it peels. Every quote we give includes full removal and preparation, because that’s what makes the new bead last. On a busy site in a large place like St Albans, a failed joint gets worse with every day of use. Catching it early keeps the fix simple.
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 you will have a fixed figure to work with.

Different surfaces, different methods
Movement joints in walls and floors
Movement joints in walls and floors let the structure expand and contract. Failed seals let grit and water in, and the edges start to suffer. The new sealant is chosen for the movement and, on floors, the traffic.
Commercial kitchens and tea points
Gaps and ragged beads trap dirt that cleaning can’t reach, and cleanability is part of what an inspector looks at. We seal to a neat, cleanable finish and work around service times you agree with us.
