Sealant Supplies Ltd Reviews 

I see I am not the only one that is complaining about unacceptable slow delivery time and especially when they were aware that I needed the product within 6 days and not later.
Now told they will first deliver next week and taking 9 days and I will have to go to B&Q which my sore back is not going to appreciate and I have no car.
Further I am told that it will just be left outside my property so anyone can take it and that is not their problem.
Wish I had read the reviews.
You would think a building supplier would want you to have your product within 3-4 days, especially when it is just one bag and I live in London and very central.
Not difficult to deliver to,
How hard is it to be efficient?
Having a happy satisfied customer is not of importance to this company.

Fast delivery & good pricing

Very poor customer service!!! They will definitely let you down with your order, very unreliable and take no responsibility for their mess ups!!!

Don't bother. Slow dispatch, slow delivery. Now on the 7th working day since ordering and looks like the item is lost by the courier. Customer service of supplier is non-existent. If they answer the phone and it was an online order they try and say their website team can only deal with it and you have to raise a ticket. Tickets just go unanswered for days. Awful.

Ease of placing order.
When company had to advise of delay - My experience was generally positive, and this is why I gave five star review.
My efforts to establish reason for delay when notified was responded to same day & I was given opportunity to choose in favour or otherwise.
I asked to be notified of any further delays and was notified of POD on the morning of delivery by this business . Ironically speedier than the courier!
When I was in touch with them on delivery they responded same day & promptly.
Sometimes things don’t always go to plan but in my opinion they demonstrated ownership of issue from the point of notification of delay till morning of delivery and frankly that for me is an expectation but not always the case with merchants ! So my experience was as good as what might be expected when problem of delay was identified. Thank you to the pro active members of the team that made a potential disappointing situation good !
I would use business again
I would recommend to friends /family

Don't even think of using this company, I'm still waiting for part of my order from 16th March (11 days) and now it's says 3 more days. Fobbed off every time I ring and promises to ring back but never done. Delivery company useless as well. It has cost me a lot of money in down time and now I'm having to order from elsewhere as I have no confidence that I'll ever see the rest of my order.

Spoke to the lady charlie on the phone, she was very helpful and made sure my grout was sent in time.

Avoid if you need anything any time soon. I placed an order almost a week ago and received no updates via email. I contacted them at the beginning of the week and was told it would be dispatched that day and arrive the next day. Two days later I was told the same story again, that they’re a day behind and the items are still at the warehouse. Safe to say iol be taking business elsewhere

Placed and order, was sent a despatch email but there was a 'problem' with the collection according to DHL. I complained and finally it arrived a week after it said it would. Parcel was badly packed, the box was falling apart with a tiny amount of brown paper.
One of the items was leaking, 2 were missing with a written message saying they would be sent.
3 of the 6 sealants have an expiration date of April, just over a month away and were missing the nozzles. One of the sprays has a smashed cap as well but luckily still works so fine.
Had to chase them about the missing items, eventually received a reply after messaging them twice saying they'd send replacement nozzles and a replacement for the leaking item. No mention of the sealants which will expire in just over a month.
New parcel arrived and all they sent were the 2 missing items!
Terrible company.
Will update my review as things progress.

Edit: They eventually sent me a replacement for the leaking item and it looks like very old stock with the label almost destroyed.
They sent replacement nozzles but refused to do anything about the silicon that is near expiration and tried to tell me that it will be ok as they've stored it very well and some rubbish about the expiry date not meaning much until it's opened?!
They have also now deleted my account and stopped communicating with me.
AVOID!

Wow I'm really impressed with this company I was needing some specific items which other online companies had let me down in supplying/fulfilling my order. Sealant supplies packed my order same-day had it shipped out and it arrived to me the next day! I couldn't be more happy 100% recommend thank you so much for your amazing service and fab customer service

Great service great products highly recommended

Fast delivery, great communication and well priced products. Looking at the reviews i fell in a predicament, i wasnt sure if i should bother. But lucky i did! I ordered on a monday recived it 3 days later in time for my job. Very kind people who talked to me on the phone and reassured me i would get it in time and they didnt disappoint. Really recommend thank you very much SSL!

Good customer service and excellent price for the product

Excellent customer service as always.
Friendly people with a personal touch.
Thank you Charlie and Mike

Excellent customer service and responsive. Purchased a product, needed to cancel next day. Easy to cancel and refunded no fuss
Will use this company every time now.

Waited for 2 weeks before receiving a fake shipment notification. The tracking link says they did not received the parcel from sender. I immediately asked for a refund and they agreed but the amount never show up on my account Its now been 3 weeks after the request.

In case like me you have ordered from Sealant Supplies then read these reviews and thought "Oh no! Is it going to arrive in a reasonable time or will I have a half finished kitchen at Christmas?!" I can tell you that my order did arrive on time. I ordered on Sunday night and it was delivered on Thursday.

Poor delivery times.
The website quotes 48 hour dispatch times and 5-7 working days delivery times.
However, my order took 13 days to arrive.
Products seem good but let down by their delivery system.
My order was also delayed with DHL who couldn't give me an udpate either.

Ordered on 08/10/25. After the same day confirmation email not a word from them for a week. Emailed them, they said sorry for the delay supplier did not inform them the 1 Yellow and 1 Black sealant I ordered was out of stock but will be with me on Friday (9 days after order placed) Friday came and gone, then Monday....No delivery. Emailed them again, They're sorry, now my order is definitely on it's way, will be with me on 23/10/25, Thursday. Well, the black turned up. 1 Hour later a bucket of Mapei grout I never ordered also came, obviously somebody else's order...
Emailed them about the yellow sealant, they said the supplier just told them that it is now discontinued. 15 days down the drain. I could have picked up a black sealant in 10 mins at any local merchant, I needed the yellow but that never came now was I informed that it will never come.
Save yourself a headache and stay away from this company.
