Maintenance after handover
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Have extract fans checked so wet areas dry out
- Deal with small splits before they become leaks
- Look at the sealant around anything that has been moved or replaced
- Keep abrasive pads and scrapers off resealed joints
New joints need their full cure time before they take water, cleaning or traffic. Cure time varies with the product, conditions and depth of the joint. Leaving the area closed until then keeps the bead neat.
Occupiers often notice failing sealant before the facilities team does, and in a hotel, office or shop it makes the whole space look neglected. Planned replacement saves fielding the same complaint again and again.
Commercial sealant contractors in Tyttenhanger
Mastic Doctor has been sealing joints for businesses and contractors since 2005: CHAS accredited, Constructionline member, five million pounds of public liability insurance and CSCS-carded applicators. If your site needs RAMS, an insurance certificate or CSCS details, say so and we’ll confirm with the quote. We work on window and door perimeters, washrooms and tea points and movement joints in walls and floors, and what we are called in for most is smeared sealant across finishes from a rushed job and frame mastic that has hardened and come away from the wall. Looking for mastic applicators who cover Tyttenhanger? We have been sealing commercial buildings since 2005.
On a typical commercial building in Tyttenhanger, the joints that fail first are the hardest-worked ones: south-facing perimeters, entrance thresholds and busy washrooms.
Business units in the countryside around places like Tyttenhanger are often converted barns, stables or farmyards. Their mix of old walls with new frames, partitions and floors means many joints between unlike materials, and a sealant colour that suits the building’s character is often part of the brief.
Whoever the client is, the cover is the same: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Questions we are asked in Tyttenhanger
Do hotels near Tyttenhanger have to close for sealant work?
In most cases no closure is needed: we work room by room or floor by floor. We agree the order of rooms and the timings with you before we start.
Is Tyttenhanger too far out for you?
No. Small places get the same service as large ones. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.
Can you supply RAMS and insurance details?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We hold CHAS accreditation and Constructionline membership and carry five million pounds of public liability insurance.
Are your applicators CSCS-carded?
Yes. Should the site need card details in advance, tell us and we will confirm them with the quote.
Can areas stay open during the work?
Most of the buildings we work in stay occupied. Only the area being sealed is closed, and the sequence is agreed in advance for as long as the cure needs.
Does the weather affect the work?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
Can one contractor look after sealant on all our buildings?
Yes, we can. Give us the sites and the scope at each, and we’ll put together a fixed quote and a sensible order of work.
What Tyttenhanger’s businesses ask us to seal
Tyttenhanger has at least three named business or industrial parks inside a 3-mile radius. Sites like these see regular refits, with shopfronts, offices and staff areas to seal. There are a number of hotels within about 2 miles of Tyttenhanger. A hotel refurbishment is full of joints that guests will see, and a matched colour keeps them discreet.
Retail sites such as The Albert Bygrave Retail Park, 0.8 miles south-west of Tyttenhanger, are typical of where shop-fit joints, frontages and staff areas need neat, colour-matched sealant. Shops and cafés around stations like St Albans station, 1.7 miles to the north-west of Tyttenhanger, trade from early, so work is timed around them.

Honest limits
Before quoting, we check that sealant is the right answer. It isn’t the answer for:
- Broken glass or blown double-glazed units
- Walls or slabs moving more than any sealant can take
- Water from a services leak rather than a joint
If in doubt, call 01277 525 020 or email drawings and photos and we’ll say what we think before you book.

What we’re called out for in Tyttenhanger
The wrong sealant in the wrong place is a common cause of early failure. Decorators’ caulk on a joint that moves, acetoxy silicone on stone or metal, or a stiff sealant on a facade. Guidance such as BS 6213 exists to steer sealant selection for exactly this reason.
Common reasons buildings call us in:
- Greasy, split joints in a kitchen or tea point
- Frame mastic that has hardened and come away from the wall
- Weathered facade sealant that no longer flexes
- Layers of sealant, all of them failing
Sites a few miles apart, such as The Albert Bygrave Retail Park and North Orbital Commercial Park, can share one programme and one point of contact.
Questions to ask before you book
- Will failed sealant be removed rather than covered?
