It depends on the job, so we quote each one individually. To get one, call 0345 464 0079 or drop us an email with a short description of the job.
Can you add a movement joint to a tiled floor?

Floor joint sealing for homes and businesses in Summertown
The gap under a skirting board often opens as floors and walls move with the seasons. Caulk tends to crack there, so we close it with a flexible sealant instead. We are often asked to deal with cracked grout where a tiled floor needs a movement joint and gaps at thresholds between rooms, on concrete floor joints, tiled floors and commercial floors.
Where new homes go up in smaller places like Summertown, 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.

Why act early in Summertown
Caulk is quick and cheap, but it cracks where the joint moves or gets wet, so the gap reappears. A flexible sealant stretches instead. In a smaller place like Summertown, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Combining jobs into one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. We’ll give you a clear quote for the lot.

How the visit works
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a few hours, depending on the length of joint. Parking around Summertown is usually easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- We start by looking at the floor, the gap and the traffic, then choose the product.
- Old caulk, grout or sealant is removed from the joint.
- We clean and vacuum the joint and fit backing where the depth needs setting.
- A flexible sealant, or a floor-joint sealant for concrete, is applied in a colour to suit.
- We tool the joint neatly and tell you when it can be walked on and cleaned.
How to prepare
- Keep pets and children clear of the area while we work
- Let us know about stairs, lifts or work at height
- Move anything stored near the joints
Ask for a quote
Asking for a quote is easy: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job, and we’ll take it from there.

DIY versus a professional finish
If you’ve already had a go yourself, that’s fine. We cut it out and start again, 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. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
For landlords and businesses
Landlords and letting agents in Summertown can book us as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order.
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Lift furniture rather than dragging it across joints
- Check the sealant is paintable before decorating
- Mark off resealed joints in warehouses
- Use a well-wrung mop rather than flooding the floor
In commercial units, keep pallet trucks and heavy wheels off new joints until they’ve cured. Mark the area off so drivers avoid it.
Small gaps are quick to seal. Left alone, they collect dirt and widen.
Do you need floor joint sealing in Summertown?
Decorators’ caulk is often used along skirting because it’s cheap and paintable. In a joint that moves or gets wet, it splits so the gap reappears.
Most people get in touch when they notice one of these:
- Dirt and water collecting in open floor joints
- Concrete floor joints that have broken down
- Failed seals where bathroom floors meet baths and panels
- Gaps opening between the floor and skirting
Managing a site like Summer Fields School? Then floor and threshold joints in busy corridors wear quickly and are best resealed early.
Questions to ask before booking
- Are they insured?
- Whether they seal over old material or remove it
- How much experience the applicator has
- What happens if the job turns out different
How we quote for floor joint sealing

What you pay reflects the work, not guesswork. That’s why we ask about the job first.
What to tell us for a quote

- What’s wrong with the joints now
- How many joints, rooms or windows are involved
- Whether it’s a home or a business

Floor joint sealing around Summertown
Floors around Oxfordshire run from suspended timber in older homes to concrete in newer houses and units, and each moves in its own way. The joint at the skirting or threshold has to allow for that.
Rented homes near Oxford station change hands often, and open skirting and floor joints collect dirt and water, so seal them while the property is empty. For buildings such as Church of St Michael and All Angels, floor and skirting joints in halls and kitchens wear like any others.
