EDIT: (29-Jul-21) All credit to Harts and John for their customer service. They have been quick to come out and inspect the shed and silicone seal any holes and gaps. They also sealed gaps between the roof and the sides and left a tube of silicone - if I spot anything. They are also quite willing to come out again if necessary to rectify any problems (should they arise). They did explain why there may be visible day-light through the tongue-grove, and this is to allow for some expansion. Also the gap between the roof and the sides are present for ventilation in summer and advised installing a vent if the gaps are sealed. Only time will tell if there is any condensation build up or not. I've increased my rating to 4 stars Original Review: I ordered my shed from Harts in 2020, shortly after the first lockdown. There was a long wait for the shed, but there was a backlog, so I waited. I think it arrived in October. My initial impressions of the shed were good, it looked really well built. However I have come to realise, it’s probably one of the WORST purchases I have ever made. With the shed you get a warning about condensation and to keep the shed aired. I’ve had sheds in the past, and never had such warnings. But despite trying to open the shed as often as I could, come January/February, there was mould on the inside. Great. But in my opinion I don’t believe this is anything to do with me not opening the shed up often enough, it think it’s the poor design and quality of the shed. I’ve had sheds in the past - never had problems with mould and the shed would be closed all winter. Spoke to others, no problems with mould in their sheds over winter. I think the problem is the fact the shed is not well sealed. I think it lets moist air in or it’s letting in rain somewhere! The roof has an overhang, with about a centimetre gap. The timber itself is low quality with hundreds of knots in it, some of which were not filled in by the fitters. The tongue and grooves of the boards themselves do not fit tight together! In summer this is apparent, as you can see daylight through the gaps! If daylight can get in, so can moist damp air and possibly rain. In summary: the shed looks great, but it’s poor quality timber, poorly fitted together, and a waste of £550 that I spent.

After visiting a few different shed companies I decided to go with Harts Timber Sheds as I was impressed with the quality and price. The shed was manufactured in 2 weeks and has just been installed in my garden. The lads put the shed up in just half an hour, very pleased! Would recommend.

Brilliant service from start to finish, added extra shelf as requested and delivery date agreed. Lads turned up exactly on time and as agreed and she’s was built within 45 minutes, loads of advice and very friendly installers, highly recommend this company for a great service and great price 👍

Took delivery today of my shed delighted with both product and especially the 2 delivery gents who get me posted with delivery time and did a great job of install ,, Katie Bradley

We ordered our shed and it was delivered and installed within the week which I think I s a fantastic turn around. It was installed within 30 minutes and they gave us advice on what to paint it with too. In my opinion (compared to other companies that deliver and install) they were fantastic value for money.

I bought a shed off harts 8x12ft it was delivered within a couple of days after I ordered I was very impressed with the delivery and the prompt service.The shed was put up in less then one hour .I am very happy with the quality. I would like to thank the company and workforce for being so prompt and courteous.

Great priced sheds, top quality. Turned up on time, also took my old one away. Nice set of instructions on how to preserve your shed with timber oil. It does arrive with a coating of preservative. With the shed having a smooth coating on the outside it was possible to apply another coat of timber oil with a roller, rather than a brush which was much quickee.

Delivered the shed at a time convenient for me (before work) and had it finished very efficiently.

A big thanks to all at Harts sheds excellent service from ordering to delivery & erection. We will definitely use again meny thanks Iain & Julia Fraser ☆☆☆☆☆ A+.

Brilliant service. Arrived early and put up shed in no time. Highly recommended for value too.

Guys who delivered shed were excellent, rang prior to arrival and arrived on time. Shed installed in 30 mins. Excellent quality

Summer house fitted this morning the two lads were brilliant, couldn't do enough for me, summerhouse is fabulous, going to insulate and plyline the inside for winter use, thanks again.

We had a couple of the lads down earlier today to fit our new 12 by 5 shed on a really hot day. Everything was booked in really easily and when they arrived everything was done in 20 minutes. Really nice people and a top shed. I cant fault anything about the whole experience. I have and will be recommending them to family and friends

Spot on from start to finish. Accommodated my requests for size, height and window position with no quibble. A couple of the spaces weren't very generous, but the team that turned up didn't make any bones. They were quick, tidy and very professional - highly recommend.

Fantastic service. Fitters were super speedy and helpful.

I ordered the sheds through Linnyshaw Garden Centre Walkden. They arrived on time and were expertly put up by two men who were very polite and friendly. They look great (that is the sheds) and I was given a leaflet to advise me on the maintenance. Overall very pleased with Linnyshaw Garden Centre and Harts Sheds.

Impressed with the quality of the shed. Erected very quickly. Would recommend without hesitation. Thank you.

Ordered the shed in Westhoughton, agreed delivery date. Arrived as agreed, and quickly erected shed. Efficient and friendly. Great price, great chaps, great shed.
