DIY sealant or a professional job?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
What we are called out for in Harwich
If the sealant is too shallow, has the wrong backing or sits on a dusty surface, it is not installed as tested. Rushed fire stopping is common, especially where it was squeezed in at the end of a project.
Keep an eye out for any of the following:
- Gaps filled with a product that isn’t fire-rated
- Fire stopping disturbed by later work
- Open gaps behind door architraves
- Gaps around pipes and cables through fire-resisting walls
For landlords with property near Dovercourt station, any gap left by new services in shared walls should be closed with a fire-rated product.
Before you book anyone
- How the joint is cleaned and prepared
- How much experience the applicator has
- How hidden problems are handled
- Whether the sealant suits the joint
Why act early in Harwich
An unsealed gap lets smoke and fire get round a wall that was built to hold them back. A proper seal lets the wall do its job again, and the work involved is often modest. In a family home in Harwich, a failed seal around a bath or a frame lets water into places you can’t see, like the floor under a bath, the back of a panel or the inside of a wall. Whatever the joint, failed sealant only gets worse.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we’ll go through it with you.
Why us?
- Any old sealant cut out fully, not covered over
- Anti-fungal sanitary silicone in wet areas

Fire rated sealant in Harwich: local notes
For seaside hotels, guest houses and holiday lets around Harwich, heavy use in the busy months is hard on washroom and kitchen sealant, and any building work there should leave fire-rated joints made good. Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, and gaps around services are often picked up there. We work to the specification you’re given, installing the product to its tested details.
For site and facilities teams at buildings such as Harwich and Dovercourt High School, fire-stopping around service openings should be restored whenever new services go in. If you look after a church, hall or community building such as Church of All Saints, older buildings that have had new heating or wiring often have service gaps worth checking.

Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Check whether a sealant can be painted before decorating over it
- Photograph sealed gaps before they’re covered up
- Ask every contractor to reseal any fire stopping they disturb
- Include hidden areas like risers in routine checks
Tell other trades that the gaps have been sealed, and make sure anything they disturb is resealed with a suitable product. Later work is a common cause of damaged fire stopping.
Leave a fire-stopping gap open and smoke can move through the building much more easily. Closing it is generally a straightforward job.
What we do, step by step
On the day, we look over the joints with you first, so you know exactly what we’re doing. We protect the surfaces around the joints before any work begins. Most jobs take anything from a few hours to several days, depending on how many gaps there are. Parking in a town like Harwich is normally straightforward, but tell us if there’s a driveway or any restrictions, and mention if the work is upstairs, in a flat or high on the outside.
- We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
- We measure every gap and note what it’s in and what passes through.
- Unsuitable material such as ordinary foam or silicone is cut out.
- We fit backing where needed and apply the fire-rated sealant to depth.
- Every location is recorded with the product used.
How to prepare
- Mention any parking rules near the property
- Where the joints are inside, avoid wetting them before we arrive
- Mention any sign-in or site rules at work premises
