Greenhouse erection is up..but will it stay up??

Posted: 17/06/2013 at 23:30

Well - finally - my greenhouse is up.

I have a couple of questions however...

I tried to make my greenhouse as square/level as possible. The final aint square or level but its..close. The glass all fits ( bar a couple of sheets a few millimeters out but got them in ), everything works and looks..ok.

But, the sides do appear to bow out slightly...certainly a curve going on if you look down the guttering..definately bow/bend shape slightly. Also, the roof - the bar going across the roof..certainly isnt level..again..seems to bend..slightly.

Now, my granddads/dads greenhouse up for years literally were leaning at 45 degree angles!! not overly concerned..but would be interested to know...why isnt dead level/square/staight.

Surprised at how..loose..well..wobbly...i mean..just weak to touch the backend of the greenhouse is. All else appears solid enough but the backend does appear..unsupported lets say. That a common feature? Im not missing any pieces etc

Finally..the glass is in..but..i didnt look properly at the instructions and didnt place the butterfly clips in the correct spaces..aka 12mm in the corners of some panes etc..Now, i have tried to rectify this and re-did a few of the panes...but i cant reach one side of the greenhouse because its now too close to the garage etc..

How important are those the right spaces? I note..water already seems to be logged inbetween the roof panes ( where the two glass panes meet/overlap clips hold them ) well theres a ridge of water there. Even on the panes which are properly butterfly clipped in

Any reason for this?

Any any tool that can take out and put in those butterfly clips? because my fingertips are hurting right now!!


So ,theres 4 questions..that aside..happy its up and i cemented the base although i feel it kinda slides on the base if you push it ( well it did before all the glass was is only joined to the base via 12 small clips after all )..but feel i didnt do too bad a job. The spiders already seem to find it a nice place to call home!

Nightmare - keeping a greenhouse base level!

Trying from PC..converted photo to Gif or Jpeg..nothing.

Anyway, all it was showing was the base of a greenhouse, metal 'spike' attached downwards..heading into a hole Ive dug. The corners of the base..are not meeting properly..the metal spike attached correctly  (assuming its meant to sit downwards?? into the ground?? instructions dont tell me!! ..not meant too sit upwards is it? )  Just the edges arnt meeting perfectly..not bad..but not perfect...and hence...the whole thing isnt level etc..

Yes, aware of measuring squareness..but really its the getting whole thing level.

And..cementing in the 4 edges/ 2 in the middle metal 'spikes'. Getting them too stick.

I have tried to upload a photo..appears easy to do..but doesnt upload?? whats up with the site?  Just too see if im right re the metal spikes and best approach.

I have dug 6 holes, sat the base in there..but..not flat on the more cement to build a 'ridge' perhaps to settle it in.

Any advice on upload photos!!

Literally tearing my hair out now and havent even begun on constructing the greenhouse.

THE BASE....I cant seem to get the thing square..well i can..but then its not horizonal..and when i ..just about get the thing level...the back end of it is not the same height as the front end!! AND...

..the 6 spikes I have, just shortish metal pieces, do not stick into the ground. i have cemented them in..but this morning find they are loose..aka..frame can be lifted out ( just as well as have to start again anyway!! )

Any suggesting please! Its 6ft x 10ft. The metal base...i assume is flat..but could be a little have been lifting it up etc I note that when i bolt it together the edges ..although fit corners..I wouldnt say its a snug fit..a line of gap...but the joint is bound together ok.

Its lying on a laid piece of cement...again...trying to get a 10 x6 and bigger concrete base all level..done in stages..aint easy..and its not level..however..i dug 6 holes, in corners and two at the sides..and lay the base in with the metal 'spikes' falling into the holes and I cemented it. No matter how many times I tried..and i really did correct the that its 100% was impossible to be deadon all the way around ( even if it meant lifting the base off the concrete floor..gaps fill later )

And the fact that the spikes aint stuck? any thoughts? In the poor instructions did say to use...piping?? none supplied.. I mean what do you do..stick the metal spikes in piping? and then cement??

Boring old problem i know..sorry..but any thoughts welcome. How can I get this blasted frame 100% square and level on all sides? Does it have too be???? I keep hearing about nightmare fitting glass if its not. No room for 99./9% accurate then?


update...greenhouse on breezeblocks..attaching base???

Posted: 28/05/2013 at 21:09

Right - sorted. This evening  - with a heavy heart - I knocked down my square/level breezeblock wall which essentially cost £25 in blocks and £15 in sand/cement and more importantly 2 days of time and an aching back.

I was about to screw the first part of the base..the front part.. when it just looked so..close to the edge ( has to be for the sliding door ) and was just slightly out i thought..clearly this is just the start of my problems.

So, a hammer in hand..i now have an impressive amount of rubblie in my garden. I have already laid the few of 3 sections of new cement..level this time. To form my base.

Hopefully, if the weather holds, I will be in a position to lay the base, cement it in ( seeing as my new cement will hardly have set yet )..and perhaps next week start building my greenhouse.

I think it was for the best dont you!  Thanks for all the advice.

Nutcutlet and all other replies. THANK YOU once again for time taken. Appreciated. And oneday will upload a photo or two. I hear will be a sunny week the end of greenhouse will up up! and cuttings etc will proceed. heart is saying..keep it simple..and jsut have a step up..i hate the thought of a step in though!! and as I have already built my mini wall complete with 2ft gap for'Do It already!!' .

I'm no dad seems to might be ok..but end of the day..stop messing about and knock down my breezeblock wall etc ( which will soak up the water anyway and create moss etc etc who knows!! )

I REALLY would love to know Nutculet...this idea of the door frame struts...not having erected the greenhouse yet ( and the instuctions are scary!! )...will i simply be able to make these 'struts'cement into the ground perhaps...when you say a bit of a project...basically....

..i plan to my base to the breezewall. I have my bolts etc..and then erect the structure...and then....then use a hacksaw etc and cut through the base and the thin aluminum strip. I will then..ensure..the struts? are firmly in place? My main concern then is the door...naturally a gap at the bottom. I intend to extend with a couple of stips and some glass or plastic the door..


Right? Any other thoughts on what could go wrong? I think the Base...could it perhaps..twist..its 6ft across..will be properly fixed in..and i cut out the mid 2ft section of it..MORE POSITIVE REPLIES PLEASE!!! I dont like it when people say...'seriously weaken the structure' !!!!!! I mean..just spent £500 on this..and plan to cut it up!!! i know..i know....

I need help! Base for Greenhouse

Posted: 28/05/2013 at 12:25

Although i can't help with advice - sorry - intrested in your plight. As im currently in a greenhouse base situation. I have a concrete base and ..due to 'experiance' of banging my head on the greenhouse ( im only 5ft 10 mind you ) i chose to heighten the thing. Two flat breezeblocks laid - all straight and square ( i hope ).

Now..i have the doorway situation. Do I cut the base/thin aluminum strip for doorway ( so no need for horrible step down / up ) and risk...weakening the structure??? or not.

Wall is built..with 2ft gap for door..and small jigsaw in i sense my brain is saying go for it...but im thinking of the ground frost and extra warmth a short wall will perhaps bring...realise breezeblocks soak up the water cant win.

Sand...on the floor..pebbles...etc..imagine all the compost etc falling into that..ants..bugs etc....I'm raising one section slightly and filling with a little compost - which in theory I can then clean/reuse. Other side slabs..simple. No messing.

Thanks Skyrunner/Fairygirl for replyies. Glad to hear Sky that not just me then wanting to heighten te greenhouse. easy enough to screw/bolt down the base. I suppose my own real question then is...How big an issue would it be for me t cut the base/frame where the door currently would sit?

I mean..seriously..will this really weaken the structre ? End of the day the doorway itself divides up the greenhouse doesnt it...a thin strip of aluminim wouldnt really effect the overal structure of the greenhouse would it?

I will take also be using a hacksaw to cut the base etc..wish me luck. APPRECIATE any replies...before I set about an 'destroy' my new greenhouse! ...thanks.

At the moment my main concern is bolting base to breezeblock and cutting the alminum esp the base section. 

Re the doorframe and contacting tig welders etc..thats all out of my league and budget im afraid! I will mess about with the door iteself/extend etc

Photos taken - still to upload however - at the moment its just a wouldnt be of much help i dont think..saying that...i will tomorrow upload a photo.

Essentially, a breezeblock wall, 2 high ( laying flat ), have measured and left a gap for where the door will be.

The base will laying on top of the breezeblock wall, roughly laying in the middle of the breezeblock..apart from at the front ( because obviously it needs to be level with the front for the sliding door to slide ) .

So, all I'm asking is...(a) Will cutting 2 ft of the base and 2ft of the thin alminum frame ( for the door ) weaken the structure?

(b) What shall I use to bolt down the base onto the breezeblocks? Tempted to drill a big hole an insert/cement a few of the 'spikes'. Also have to rawplug??? the base into the wall. Ok to do that?? Do I simply drill through the aluminum base? Doesnt appear to be any pre-drilled holes.

Will worry about lengthing the sliding door/sealing it/ makng a make-shift slider..another time. Main concern is cutting this base/frame. ( and any decent tool to cut alminum??

Thanks again.
