How the visit works
On the day, we look over the joints with you first, so you know exactly what we are doing. Surfaces next to the work are protected before any work begins. The work normally takes a few hours in a single home. A visit to Watford Heath is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely down to clean surfaces.
- We clean out the dust and grit left from the build.
- We prime where needed and apply a sealant suited to each joint.
- We tool every joint neatly and tell you when each area can be used.
Getting ready for the visit
- Clear items away from the joints we are working on
- Mention any parking rules near the property
- Keep children and pets away from the work area
Getting a quote
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and email photos if that’s easy.

New build mastic in Watford Heath, done properly
A new build should have a neat, sound bead at every joint. Smeared, patchy or cracked sealant is worth sorting early, before water gets into the floor or walls. We work on plot handovers, skirting & floors and windows & doors, and people most often call us about gaps behind new kitchen upstands and smeared, uneven beads picked up at snagging.
Where new homes go up in smaller places like Watford Heath, it’s often a small development or a single plot. The sealant around baths, showers, frames and skirtings needs to be right from the start.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we’ll put it right.

What happens if it’s left?
It often makes sense to do all the sealant items on a snagging list together. It’s one visit, one quote and one set of cure times. Around Watford Heath, water from a failed joint in an older home can soak into timber and plaster, and that is a much bigger job than renewing the sealant.
Combining jobs into one visit generally makes better use of the time than several visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

Surface by surface
Kitchens
New-kitchen sealant is often applied in a rush. We take it out and reseal neatly, colour-matched where it shows.
Show homes
We can refresh show-home sealant that has discoloured or been knocked. The old bead comes out and a clean new one goes in.
Can I do it myself?
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 does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
Watford Heath questions
Can you help a landlord with a rental near Bushey station?
Yes, landlords and agents are among the people we work for. Just ring 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll send you a clear quote.
Will you come out to Watford Heath?
Yes, Watford Heath 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 reseal over the builder’s sealant?
No. Sealing over old sealant looks fine for a few weeks, then lifts. We remove every bit of the old bead before resealing.
Should I try DIY first?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
Is there any odour?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
When is the sealant fully cured?
Different products cure at different speeds, so follow the cure time we give you when we finish.
Can you work on commercial sites?
Yes, regularly. We can plan bigger jobs in stages to suit the site.
What sealant do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We explain the product when we quote.
What affects the quote in Watford Heath
For a quick quote, just ask. The main things that affect it are:
- How many areas need sealing
- When we can work, for business premises
- How easy the joints are to reach
- How much there is to do
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
