How to extend the lifespan of your conservatory

A conservatory built to a high standard by a reputable builder should last for 10 years, minimum. However, with the right care and maintenance, a conservatory can be made to last for several decades. For most people, installing an extension to their homes like this is an expensive undertaking. It’s important that you get the most for your money – so read on for our tips on extending the lifespan of your conservatory.

Reputable construction

The first step is the most important of all, securing a builder with a solid reputation and a wealth of experience. Pick a company that’s been in business for a number of years. That way, they will have a track record you can research in advance. If their conservatories leak after only two years, you won’t have to install one to find out. A reputable builder will also guarantee their work, usually for a minimum of ten years.

Material choice

Nowadays, the material you choose when building a conservatory is less important than in the past. However, alternative material types do offer different advantages and disadvantages. Many opt for polycarbonate or glass, both of which often need replacing after ten years. It is not the glass that deteriorates but the rubber gasket that holds them to the frame. This will cause leaks if not managed properly. The best way to extend the roof’s lifespan is to get it done right in the first place.

The frame’s material will also determine how long the conservatory will last. Modern conservatories are usually built with white PVC, but there are a number of other options on the market. Wood offers a rustic, more traditional appeal, but necessitates frequent upkeep. If the beams are properly seasoned prior to installation, the wooden frame should stand for decades – when combined with a vigorous cleaning, resealing and painting every two or three years. Aluminium frames are also becoming more popular, although generally only with modern housing. These will resist rust and the elements particularly well.


It is good practice to incorporate your conservatory into any weekly or fortnightly cleaning schedule you might have. Stay on top of guttering maintenance, ensuring that they do not become blocked. Regular overflowing may cause damage to your conservatory. Likewise, clean the windows inside and out, paying particular attention to the sealing around the windows. Over time, these can become grubby or discoloured. All it takes it a regular wash with soapy water to keep them looking their best.


The final issue is one that requires the attention of every conservatory owner. Condensation is a plague on conservatories all across the UK, particularly when they are not used often enough. Heating and airflow should be something you consider prior to installation, to ensure that the temperature and moisture level in the conservatory matches that of the rest of your home. Without taking this precaution, the inside of your conservatory might even become mouldy over time, an issue that will exacerbate the problem and force you into making more costly repairs.
