Polycarbonate greenhouses are becoming more and more popular. Every gardener should be aware that correct installation alone is not enough for long-term and trouble-free operation, as well as which polycarbonate is best used for greenhouses.

How to carry out scheduled repairs?

Scheduled greenhouse maintenance begins with an inspection of the entire structure. Inspection is carried out twice a year. The first time - in the spring, before the planting begins, the second - at the end of the season, in the fall. Also, do not forget about caring for your polycarbonate greenhouse in winter.

The best time to do this is on a clear and sunny day without precipitation. This will protect parts and elements from unwanted moisture ingress, which can lead to further failures.

Inspection will require a careful examination of all structural elements of the greenhouse. First of all, you need to carefully examine the coating itself for the presence of cloudiness, swelling, cracks, dents or any other deformations on it.

Following the coating, the frame is examined. It is necessary to check whether it has suffered during the downtime, whether the precipitation of the support has been washed away, whether the frame products are installed evenly. Corrosion could appear on the parts, then they need to be cleaned and covered with a layer of paint.

When examining the frame, an ordinary level is useful. They can check the position of the building, it should be located strictly horizontally.

If no shortcomings were found, then you can start using. Before that, you need to wash the greenhouse from the outside and inside.

Polycarbonate panels are cleaned with a sponge or cloth with warm water and detergents without alkalis or other aggressive substances. After - rinse everything with clean water.

Strength check

It is important to make sure strength and stability of the greenhouse... If it is necessary to strengthen the polycarbonate greenhouse, then it will be optimal to install the strapping rings around the perimeter. If necessary, strengthen the frame, then you need to strengthen the area at the base of the building and in the center.

It is also possible to mount load-bearing columns that will take on the main load. It is recommended to install them along the entire greenhouse at regular intervals of at least one meter.

Surface preparation

The surfaces of even the highest quality materials begin to deteriorate over time. Therefore it is important pay attention to cleaning surfaces... Corrosion, mold and other formations can lead to irreparable damage over time.

At the first signs of such flaws, you need to thoroughly clean the problem area with fine-grained sandpaper, then cover it with an antiseptic compound, paint and varnish or anti-corrosion enamel.

It is recommended to periodically paint the entire frame. This will not only keep it intact and protect it from corrosion, but also improve the appearance of the entire greenhouse. Paint for outdoor use is best suited, it is resistant to high humidity, different temperature conditions and the effects of fertilizers and chemicals.

Additionally, you can strengthen wooden parts by covering them with a layer of epoxy resin, and on top of it, apply a layer of varnish or paint.

Sudden breakdowns and unplanned repairs

However, even with regular checks and preventive maintenance, the possibility of any breakage cannot be completely ruled out... Depending on the nature of the problem, appropriate solutions must be selected. Do-it-yourself polycarbonate greenhouse repairs must be carried out as soon as possible, so as not to aggravate the problem and have time to prepare the greenhouse for the new season.
The video below will help to repair the greenhouse with your own hands.

Foundation destruction

The occurrence of such a problem is unlikely, but if this does happen, then the situation can be corrected.

In such a situation, the structure is completely dismantled and assembled on a new basis. It is preferable to make a base for a greenhouse made of polycarbonate.
If the concrete foundation has cracked, then it is also possible to repair it. First you need to dig a hole in the place of the breakdown. You need to try to do everything as carefully as possible so as not to enlarge the crack.

After that, you need to fill the gap with a solution. It is necessary to fill in the solution until the moment when it ceases to be absorbed.

Frame faults

As the basis of the structure, the frame is subjected to the greatest stresses. The brittleness of the material can be the cause of breakdowns., incorrect installation, violation of the position of the frame due to water washing. In case of untimely maintenance, cracks and other deformations can form in parts. Often, frame breakdowns are associated with the impact of heavy snowfalls or gusty winds.

Bent metal parts can be straightened, and broken boards can be replaced or nailed on top of them intact. To avoid further breakdowns, it is better to additionally strengthen the place of malfunction.

As with other work, frame repairs are best done on a clear, dry day in temperatures above freezing.

Panel breakage

Damage to the coating does not always require replacement and you can fix the situation yourself.

Polycarbonate panels may change its shape under the influence of temperatures... In this case, it is sufficient to reinstall the panel, leaving a small gap.

If cloudy and dark places are formed on the polycarbonate surface, then you need to make sure that the sheet is installed with a protective layer outward. However, if the damage occurs over a large area, then it is recommended to replace the panel.

If moisture appears in the honeycomb, then the coating must be dismantled, and then blown and dry well.

The most difficult and unpleasant breakage is cracks. But even such damage can be repaired. Such cracks are filled with silicone or roofing sealant.

However, if the hole is large, then the only solution is to replace the entire panel. Moreover, if the panel is rectangular, then you can cut out the damaged fragment, and install a whole one in its place, while strengthening the seams.

But in the case of structures of an arched or other complex shape, it will be necessary to replace polycarbonate in the greenhouse. At the time of replacement, the polycarbonate surface can be covered with a film, but it should be borne in mind that this is only a temporary measure.


Modern technologies presented very convenient and practical material for greenhouses... Now you yourself can make your own polycarbonate garden greenhouses. Such greenhouses can last a long time and effectively, but subject to simple advice and regular inspections and scheduled repairs.
