How we handle coloured sealant in Boxmoor
We can agree a short trial length before the full run. Cured sealant may look a shade different from the wet bead, and lighting changes it again. Tell us who needs to approve the colour and we’ll plan for it. Most enquiries involve failed coloured sealant that has split or peeled and white or grey sealant that clashes with the finish, on office fit-out finishes, powder-coated and anodised frames and natural stone and brick. A single leaking joint is often how a building in Boxmoor first comes to us: we look at the rest while we’re there and tell you what we find.
Sealant jobs for businesses in a place the size of Boxmoor are often best grouped: shopfront, washroom, kitchen and any external joints done together. That keeps travel and disruption down.
Our workmanship is guaranteed for 12 months, in Boxmoor as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

FAQs: Boxmoor
Can you work at a site such as Chancerygate Business Centre, by Boxmoor?
Yes. We cover Boxmoor and the area around it, including industrial estates, business parks and retail parks such as Chancerygate Business Centre. To start, just call the office on 01277 525 020 or use the quote form with the unit, the joints involved and your access times.
Will our hotel in Boxmoor need to close for the work?
In most cases no closure is needed: we work room by room or floor by floor. Housekeeping and our team agree each day’s rooms.
Can we specify the colour by RAL number?
Yes. Give us the RAL reference and we’ll check it against the product’s range. You will see the nearest options at quote stage.
Do you work in Boxmoor?
Yes. Boxmoor falls within our area, and you can give us a call on 01277 525 020 or email us to get started.
What about RAMS and site documents?
Each site asks for different documents, so tell us what you need and we’ll confirm it when we quote.
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, since fresh sealant will not bond reliably to aged material.
What happens if old sealant might contain asbestos?
The duty to manage asbestos sits with the building’s dutyholder, so we will ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.
When to call us in Boxmoor
Exposure takes its toll on colour. Sunlight, dirt and pollution can darken, yellow or chalk the surface, so joints that once matched no longer do. Resealing is the chance to reset the colour.
If one of these sounds familiar, it’s time for a closer look:
- Shop fits that need consistent sealant colours across sites
- Coloured joints that have cracked with movement
- Poorly tooled joints on visible finishes
- Joints that need to match a new RAL frame colour
On a business park such as Chancerygate Business Centre (0.6 miles south-east of Boxmoor), sealant work tends to follow fit-outs: receptions, tea points, washrooms and frame perimeters.
Before you book anyone
- How the joint faces will be prepared and primed
- How the existing material will be dealt with
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Proof of insurance

What else we do in Boxmoor
What happens if it’s left?
A standard colour is quicker to source, though not always right. On visible work, the small extra effort of a colour from the product’s range pays off. Small buildings around Boxmoor suffer from failed joints as much as large ones. Catching it early means a reseal rather than repairs.
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 requirements come into it too.

Cost factors for colour-matched joints
Each job is priced on its own details. The things that drive the figure:
- Working within restricted access windows
- The size and state of each joint
- Specialist products, such as fire-rated or hygienic sealants
- Whether old sealant has to be cut out first
There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote.
What to include in your enquiry
It doesn’t need to be a full survey. A few details are enough to get going:
- Where the site is, with the postcode
- Asbestos survey details if the building is older
- Any specification or named product
- When you need the work done
A handful of photographs and a postcode is the fastest way to a quote. Send them through the quote form, or call the office on 01277 525 020 or email us if you’d rather talk the job through.
Frontages, fit-outs and joints in Boxmoor
Hemel Hempstead, one of the planned towns of the twentieth century, takes in or adjoins Boxmoor. Offices and shops from that era have normally been refitted over the years, each refit adding joints to look after. Boxmoor is about 24 miles from central London. 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.
A business with units at Chancerygate Business Centre and Frogmore Industrial Estate needn’t use two contractors for its sealant. For a hotel such as Southville Private Hotel, less than half a mile to the east of Boxmoor, the colour of a joint at the bar or the bath matters to the look of the room.
Boxmoor is about 1 mile south-west of Hemel Hempstead, in Hertfordshire. Businesses, contractors and managing agents in Boxmoor can call on us for colour-matched joints. Boxmoor is one of 371 places we cover in Hertfordshire. For work in that direction, see our London page.
