DIY sealant or a professional job?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Do not wait for the house to settle if water is getting through
- Wipe joints with warm soapy water
- Ventilate bathrooms well, especially in the first year
- Raise failed sealant with the developer while you’re covered
Photograph failed sealant before it’s redone and keep the builder’s replies. It’s useful if you need to raise other issues later.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Left alone, a small crack can become a leak.
Why act early in Plummers Plain
A quick bead over the top of the old sealant can look fine at first, but it will not bond to the old layer. A lasting seal starts with removing the old one completely. Where a wall is exposed, as many are in small places like Plummers Plain, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Combining jobs into one visit generally makes better use of the time than several visits. You’ll get one clear quote for the whole job.

What sealant work can’t fix

What the job involves on each surface
Bathrooms and en suites
New-build bathrooms and en suites are where sealant fails most often. The old sealant comes out and anti-fungal sanitary silicone goes in after cleaning and priming.
Skirting and floors
Where the floor meets a bath panel or kitchen plinth, the joint keeps mop water out. They get a flexible, water-resistant sealant.
The process
We bring everything the job needs with us, so there’s nothing for you to buy. After a quick look at the joints together, the area is protected and the work begins. Most jobs take anything from a few hours to several days, depending on the number of plots. Somewhere as small as Plummers Plain, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
Preparing for the visit
- Let us know about earlier repairs to the joints
- Keep children and pets away from the work area
- Where the joints are inside, avoid wetting them before we arrive
