About our floor joint sealing in Letchworth Garden City
Sometimes the concrete either side of a joint has already spalled. Filling against a crumbled arris won’t hold for long, so if the edges need repair before any filling, we will say so and explain how it affects the programme. We work on construction joints, forklift and pallet-truck routes and retail and showroom floors, and the usual reasons a site gets in touch are grimy joint lines spoiling a showroom floor and sealant pulled out along a truck route. Looking for mastic applicators who cover Letchworth Garden City? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
Towns such as Letchworth Garden City normally have an industrial estate or a few business units, with warehouse floors and loading areas. Smaller units can’t stop work for long, so we plan around the occupier’s hours.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we’re clear about what is covered before work starts.

Diagnose, treat, sign off
A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself normally takes anything from a day for one loading bay to several days for a large floor, split into phases, and we clear our waste as we work. For a town like Letchworth Garden City, we try to group jobs for the same client into one visit. Give us your access times and we’ll fit the work in.

- Old fill and packed debris come out until both faces are sound.

Leave it or put it right?
Open joints are where dirt collects where scrubber-driers can’t get it out. In shops, showrooms and clean production areas that matters for hygiene and appearance. Flush, filled joints leave nothing for cleaners to dig out. In Letchworth Garden City, as anywhere, the simplest time to fix a failed joint is before it leaks. Once water gets in, there’s drying out and making good as well.
No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Your questions answered
Are the floor joints in an older unit in Letchworth Garden City worth resealing?
Generally yes, provided the arrises are still in reasonable shape. Resealing with the right filler or sealant for the traffic keeps grit out and protects the arrises, and we will tell you if the edges need repairing first.
Does your area include sites such as Letchworth Gateway Retail Park, near Letchworth Garden City?
Yes. Estates, retail parks and business parks around Letchworth Garden City, Letchworth Gateway Retail Park among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.
Do you offer coloured sealant?
Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.
Can you phase floor joint work around operations?
Usually only the zone we are working in has to close. Each zone reopens when the product can take traffic and the next zone follows.
Are you CHAS accredited and on Constructionline?
Yes. We’re CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.
How do we get a quote for floor joints?
Use our quote form, or email photos and a plan, with the traffic on each area. A fixed quote follows with the product and phasing set out.
How long does a typical visit take?
That varies with the scale of the job, but the work normally takes between a day and a number of days, set by the joint lengths, the edge condition and the phasing you need. Larger or phased jobs take longer, and we will give you a timescale with the quote.
Keeping the joints sound
Your facilities or cleaning team can help the joints last. Share these points with them:
- Start with the dock areas, where joints fail soonest
- Expect fillers on young slabs to need a top-up
- Mention any aggressive cleaning regime at quote stage
- Hold traffic back until the product has cured
Once cured, the joints get cleaned along with the slab. Tell us about aggressive cleaning products or hot washing at quote stage so we choose something that tolerates them.
Edges tend to break slowly at first, then quickly. Once the first piece is out, wheels drop further and hit harder so early treatment saves a lot of trouble.
How the quote is worked out
There’s no standard rate for sealant work, since sites vary so much. What we take into account:
- The product specified
- Removal of failed or old sealant
- Induction, permit and paperwork requirements
- Distance, for remote addresses
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.
What we need to price the job
Diagnosis starts before we arrive. Tell us:
- What the building is and how it’s used
- Approximate linear metres or a joint schedule
- Clear photographs of the problem areas
- Anything awkward about access or site hours
Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.

Site staff or a sealant specialist?
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
