DIY sealant or a professional job?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Remedial sealant in Hempstead, done properly
The wrong product in the wrong joint fails however neatly it’s applied. We take it out and use a sealant made for that joint. We work on shrunken worktop sealant, mouldy bath & shower sealant and failed movement joints, and common reasons people get in touch are repeat leaks from the same joint and kitchen joints letting water behind the worktop.
Around Hempstead, it’s houses and cottages rather than flats. Sealant and grout wear out here just as they do anywhere: everything old comes out before the new sealant or grout goes in.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Hempstead questions
Will you come out to Hempstead?
Yes, Hempstead is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you cover Hempstead for remedial sealant?
Yes. Our work covers London and the South East, and Hempstead is part of that. You can phone 0345 464 0079 or drop us an email and tell us what needs doing, and we will give you a clear quote.
Do you work for hotels and businesses?
Yes. We have worked for hotels, offices and other businesses.
Can I do it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
How long before the joint can be used?
That depends on the sealant used, so follow the cure time we give you.
Can you remove sealant that’s been put over old sealant?
Yes. Stripping layered sealant takes longer than a normal reseal, but it’s the only way the new joint will last.
Will there be a smell?
Sometimes, a little. Any smell clears as the sealant cures.
Do you fix expansion and movement joints?
Yes. The depth is set with backing so the sealant only bonds to the two sides.
Why it’s worth doing now in Hempstead
A joint that has failed twice will fail again unless the cause is dealt with. Finding it, whether movement, water from elsewhere or an unsuitable product, ends the cycle. Around Hempstead, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we will explain what it covers.

The process
We bring everything the job needs with us, so you do not need to buy or prepare anything. Once we’ve agreed what’s being done, we protect the area and start. It normally takes a few hours for most joints, depending on how much old sealant has to come out. In a small place like Hempstead, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we work out whether the problem is the sealant, movement or a leak.
- Each layer is cut out and the residue cleaned off.
- We treat any mould and dry the joint thoroughly.
- The right product goes in, with backing where the joint moves.
- The joint is tooled and you are told about anything else we found.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Let us know about earlier repairs to the joints
- Plan for the work area to be out of bounds to pets and children
Ask for a quote
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints.

Leaking trays & enclosures
Repeat shower leaks often come from a tray that flexes or an enclosure sealed in the wrong place. We check both before any new sealant goes on.
Windows & doors
Wrong-coloured or messy mastic can be replaced for appearance too, in a colour that suits the frame.
Landlord and commercial work in Hempstead
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
If you manage several properties in or around Hempstead, several properties can go on one quote. Send us the addresses and the work at each, and photos by email help.

Remedial sealant in Hempstead: local notes
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.

What affects the cost of remedial sealant
We quote each job individually. This is what makes a difference:
- Any mould that needs treating
- The amount of work
- The number of rooms or windows
- Working hours on commercial sites
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
What to tell us for a quote
Photos by email are helpful but not essential. Try to tell us:
- What the problem is, such as mould, gaps, leaks or cracking
- Photos by email, if that is easy
- If it’s domestic, commercial or a hotel
- Whether it has been sealed before
There’s no standard price list, as no two jobs are quite the same. Instead, we give you a clear quote for your job. To get started, phone 0345 464 0079 or email us.
Do you need remedial sealant in Hempstead?
Joint depth matters. Sealant packed too deep, or stuck to the back of the joint as well as the sides, cannot stretch, and tears at the first real movement. Backing rod or bond-breaker tape prevents it.
Keep an eye out for any of the following:
- Caulk or the wrong sealant used in a wet area
- Worktop sealant that has shrunk and split
- Sealant applied over old sealant that has lifted
- Thick, messy sealant smeared over tiles
For an older house near a landmark such as Church of St Andrew, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.
