Remedial sealant for homes and businesses in Hertford
A joint that keeps letting you down needs more than another bead. Send photos when you ring 0345 464 0079 or drop us an email, along with when it was last resealed. If you have kitchen joints letting water behind the worktop and a second bead peeling off the first, we can help, on failed movement joints, expansion joints and mouldy bath & shower sealant alike.
Most bathrooms in a town like Hertford are in family homes, used every day, where sealant and grout take a lot of daily wear. Black mould along the bath, a lifting bead by the sink or crumbling grout in the shower are the usual signs.
You are covered for a year from the day we finish. If there’s a problem with it, please phone 0345 464 0079 or send us an email.

What we do, step by step
At the end, we look at the finished work together and explain the cure time. The visit itself generally takes a few hours for a typical bath or shower, longer where several layers have been applied, depending on the size of the job. Parking in a town like Hertford 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.
- Surrounding tiles, trays and frames are protected first.
- Every layer of failed sealant is stripped out.
- The joint is degreased and checked for movement and leaks.
- Once dry, a suitable sealant is applied and tooled.
- You get the cure time and our view on why the joint failed.
Before we arrive
- Let us know if you’ve seen damp or leaks
- Plan for the work area to be out of bounds to pets and children
- Let us know about stairs, lifts or work at height

Advice
Do you need remedial sealant in Hertford?
Movement tears sealant that is not designed for it. A bath that flexes, a tray that rocks or a building joint that opens and closes will split a rigid or thin bead.
Look out for these signs:
- Caulk or the wrong sealant used in a wet area
- Beads that never stuck properly
- Dark patches showing through the sealant
- Over-sealed joints coming away
For landlords with property near Hertford East station, botched sealant from a previous quick fix is easier to strip out between tenants.
Questions to ask before booking
- How long the guarantee is
- Whether all the old sealant comes out first
- How the colour is chosen
- When the joint can take water or movement

Work for landlords, hotels and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
If you manage several properties in or around Hertford, several properties can be quoted together. Send us the addresses and the work at each.
What sealant work can’t fix
We’ll always be straight with you, so here’s what new sealant will not do:
- Movement from fittings that are not supported
- Failed tanking or loose tiles behind the sealant
- A cracked shower tray or bath (that needs repair or replacing)
Not sure which it is? You can ring 0345 464 0079 or send us an email and we will tell you honestly.
Surfaces we seal
- Mouldy bath & shower sealant
- Expansion joints
- Shrunken worktop sealant
- Botched or over-sealed joints
- Leaking tray & enclosure joints
- Failed movement joints
What happens if it’s left?
Mould under a bead cannot be reached by cleaning. The layers have to come out, and the joint treated and dried before resealing. Around Hertford, failed sealant lets water into hidden places, like the floor under a bath, the back of a panel or the inside of a wall. Left alone, that means rot, damp and a bigger repair.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Call for a quick quote and we’ll explain what it covers.
Why us?
- Anti-fungal silicone where joints get wet
- We agree the colour with you first

Hertford questions
Do you work in hotels near Hertford?
Yes, we work for hotels as well as homes and businesses. A room-by-room programme keeps most rooms in use while the work goes on.

Where is Mr Mastic based?

What should I tell you?
The location, the problem and the rough size of the job. Photos by email help too.
Do I have to be there?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Can you take off two layers of silicone?
Yes. It’s slower than a standard reseal, because every layer has to come out cleanly, but it’s the only way the new joint will last.
Will it make a mess?
Not at all. The area is protected while we work and cleaned up afterwards.

DIY sealant or a professional job?

If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
