How we handle floor joint sealing in Downham
Across Downham, we seal floor and skirting joints in homes and businesses. We start by checking the floor type and the joint, since that decides which sealant suits. We work on concrete floor joints, commercial floors and thresholds, and people most often call us about gaps opening between the floor and skirting and floor edges that trap water and grime.
Much of London’s new housing is flats in larger developments. Snagging there often goes through the developer or managing agent, and shower seals that fail early, skirting joints that open up and gaps at thresholds are all common snags.
The work is covered for a year after we finish. If anything isn’t right with it, ring 0345 464 0079 or email us.

Different surfaces, different methods
Thresholds
Thresholds between rooms meet two floors and often a door frame. We seal them with a flexible sealant that suits both sides.
Wet room and bathroom floors
In a wet room, the floor-to-wall joint is a key line of defence. We reseal it with a flexible silicone suited to wet areas.
Honest limits
To be straight with you, some problems need a different trade:
- Large cracks that need a surveyor
- A tiled floor that needs relaying
- Cracked or broken concrete slabs

Questions from Downham
Can you help a landlord with a rental near Grove Park station?
Yes. We work for letting agents and landlords as well as householders. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
Can you do floor joint sealing in Downham?
Yes. Our work covers London and the South East, and Downham is part of that. Just ring 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear price.
Can I add another job to the visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Should I try DIY first?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Are you an approved applicator?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Can grout be replaced with sealant on a tiled floor?
Often, yes, where it suits the floor. We remove the grout and seal the line with flexible sealant, giving the floor room to move.
How long before the joint can take traffic?
That varies with the sealant and the room. We give you the times for walking, cleaning and traffic when we finish so you can plan.
Can sealant along the skirting be painted?
On joints you want to paint, yes. Silicone does not take paint, so tell us your plans.
DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What affects the quote in Downham
Your quote is based on your job. We look at:
- How many areas need sealing
- The old material and how stubborn it is
- Which sealant suits the joint
- 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
Before you ask for a quote, have a think about:
- Any access issues, like height or stairs
- The address or postcode of the job
- The rough size of the job
- A few pictures by email, if you can
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and add photos by email if you can.
Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Ask before painting over a sealed joint
- Do not fill floor joints with caulk where they move or get wet
- Get cracks along tile grout lines looked at early
- Cone off fresh joints until they’re ready
Lift furniture rather than sliding it over sealed joints. Sharp edges can cut the sealant.
Water getting into floor joints in bathrooms and kitchens can damage what’s underneath. A sound seal stops that happening.
The process
We bring everything the job needs with us, so you do not need to buy or prepare anything. Once we have agreed what’s being done, we protect the area and start. It normally takes a few hours, depending on the length of joint. For a job in Downham, parking and access are the things to plan: let us know about parking, the floor we will be working on and any lift or shared entrance.
- First we check the joint and the floor and agree which sealant suits it.
- Old caulk, grout or sealant is removed from the joint.
- The joint is cleaned, vacuumed and backed where depth needs controlling.
- A flexible sealant, or a floor-joint sealant for concrete, is applied in a colour to suit.
- The joint is tooled to a neat finish and we tell you when it can take feet and a mop.
Getting ready for the visit
- Tell us if parking is tricky
- Where the joints are inside, avoid wetting them before we arrive
- Mention if the joints have been sealed before
