About our commercial sealant in Essendon
In a hotel, office or washroom, failed sealant is more than an eyesore. Cleaners struggle with it, water gets through it and people notice it. We reseal bathrooms, washrooms, welfare areas and kitchens so they look cared for again. If you have tired sealant ahead of a health and safety audit and large numbers of bathrooms needing the same work, we can put it right.
Work in a small place like Essendon is planned ahead, journey included, so it can be fitted around guests, customers or events where possible.
Your job is guaranteed for a year, as with all our work.

Workplaces and buildings in Essendon
Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
If you let a flat or house near Bayford station, sealant work can be quoted for a single flat or a whole portfolio. Managing a site like Essendon CofE (VC) Primary School? Then busy washrooms and kitchens can be resealed in phases so they stay open.

The process
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes anything from a few hours to several days, depending on the number of rooms. Somewhere like Essendon needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We start by looking at the rooms and agreeing what’s needed.
- Working hours are agreed, including early starts or out-of-hours work where it can be arranged.
- Each area is protected and stripped of old sealant.
- Once dry, every joint is resealed and tooled.
- We let your team know the cure time for every area.
How to prepare
- Let us know about stairs, lifts or work at height
- Clear items away from the joints we are working on
- Let us know if you’ve seen damp or leaks

Should I try it myself first?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Why act early in Essendon
Guests and staff judge a building by its bathrooms. Black sealant makes a clean room look dirty, and scrubbing won’t fix it. New sealant does. Where a wall is exposed, as many are in small places like Essendon, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
There are no prices on our website, because each job is priced on what it involves. Call for a quick quote and we will talk you through it.

Essendon questions
Will you come out to Essendon?
Yes, Essendon is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can you do commercial sealant in Essendon?
Yes. Our work covers London and the South East, and Essendon is part of that. Just ring 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear quote.
Can you reseal hotel rooms while we stay open?
Yes. Rooms are done a few at a time, so only a few are out of use at once. Housekeeping are told when each room can be let again.
Do you take out the old sealant first?
Yes, every time. New sealant will not bond properly to old, so the joint is cleaned back first.
Does someone need to be in?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Can you send RAMS and insurance details for our site?
We’re fully insured, and we’ll go through your site’s requirements with you. We’ll confirm what we can supply when we quote.
How soon can a room be used after resealing?
Plan for around 24 hours, or the cure time we give for that area. Planning the order of rooms keeps that downtime manageable.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. Our applicators cover Essendon, along with the rest of our area.

Common problems we fix in Essendon
A rushed reseal between guests rarely lasts. Sealing over old silicone, sealing wet joints or using the wrong product means the joint fails again soon.
Look out for any of the following:
- Worktop sealant that has shrunk and stained
- Split sealant where wet room floors meet walls
- Washrooms that need sorting before an inspection
- Washroom sealant that looks dirty however often it’s cleaned
Community buildings like Church of St Mary the Virgin are part of the picture too: its kitchen and washroom sealant needs looking after like anywhere else.
Questions to ask before you book
- Whether they’re fully insured
- How the joint is cleaned and prepared
- When the joint can take water or movement
- Whether they seal over old material or remove it
