The roof opening has stuck right before the close. It’s a twisting mechanism and it’s two bits which I think have dislodged slightly and because of that it won’t screw in full flush.

Conservatory Installer FAQs

how much is a conservatory roof?

How Much Is A Conservatory Roof?

If you’re setting a budget for your new conservatory structure or perhaps you already have one and thinking about replacing the roof, knowing how much a new conservatory roof will cost from the onset can save you a lot of headache. However, knowing the correct cost won’t be easy as this is determined by a plethora of factors which is unique to each individual. In this article, we’re going to give a rough estimate of a conservatory roof cost so as to help you make an informed decision moving forward. Let’s have a look!

In order to determine the cost of your conservatory roof, the type of roof you go for must firstly be determined. This is because there is a wide array of conservatory roof types with each having its own unique price. You can opt for the uPVC glass roof, a tiled roof or a glass roof.

With so many other factors to consider, we’ll not be able to give you an exact amount. However, in general, a conservatory roof can cost anywhere within the range of £2500 to £8500. You may also quoted for more or less depending on your roof type as well as the specifications you opt for including the size and type of your conservatory. For instance, if you own a Lean-To conservatory with a size of 3.1m by 3.1m, for a glass conservatory roof, you can expect to spend anywhere within the range of £3000 to £3500. Meanwhile for a Victorian conservatory roof with a size of 5.1m by 5.1m, the cost will range between £5000 to £8000.

Therefore the type as well as size of your conservatory really does greatly impacts the cost of your conservatory roof.

how much value does a lean to conservatory add?

When it comes to boosting the value of a property, there are a bunch of home improvements one can make to increase a property’s value. One of these improvements that can add to both the value as well as saleability of a home is a lean to conservatory. So exactly how much value does a conservatory add?

 

According to several studies carried out, a lean to conservatory should add anything within the range of 7% to 15% of the average property value in the UK. This equals thousands of pounds which ultimately translates that home and property owners can recoup some or even all of their cost of investment in the extension with relative ease. However, in order to determine the exact value added, you’d have to calculate the value of your investment. These includes determining the amount of money the lean to conservatory will cost including installation, the current value of your property as well as the amount of value the conservatory will add to your property. Doing this will help you determine how wise the investment in a lean to conservatory will be.

 

At present, the average price in the UK stands at about £240,000 and according to the experts, lean to conservatory should add with the range of 7 percent or 10 percent of that price in terms of value. In other words, the value of your property can rise by close to £17000. And if the total cost of building the lean to conservatory is about £9000, that means you’ve made a profit of up to £8,000. Besides this, there are also some other significant values and benefits offered by installing a lean to conservatory which includes more living space, aesthetic appeal and many more.

what is the difference between a conservatory and an orangery?

What Is The Difference Between A Conservatory And An Orangery?

If you’re looking to build an extension for your home, one of the first things that comes to mind is the type of structure that would best suit your property. When it comes to glass extensions there are two major varieties which includes the traditional conservatory and the orangery, but there are usually a lot of confusion over the differences of these two varieties. With the growth in popularity of glazed extensions, the differences between the two structures are becoming more and more thin. However, the main difference between a conservatory and an orangery is the number of glass incorporated. Conservatories are fully glazed structures featuring a low brick base wall, meanwhile orangeries are grand brick structures with with glazed roofs. But as a result of innovations of over the years in glazing, the difference has changed a bit.

Here are some of the major differences between a conservatory and an orangery.

✓ Orangeries are generally best suited to traditional-styled homes or with older property making use of matching stone or brick in construction. Meanwhile for a more recent or modern property, a conservatory will be the better option to add the flair to your property.

✓ Conservatories tend to be larger than orangeries, therefore if you want a smaller extension, an orangery would be your best bet.

✓ Orangeries are typically rectangular in shape and is traditionally a more regular building meanwhile a conservatory can be shaped to suit your needs. With an conservatory, you can get a T-shaped, L-shaped, curved, double ended and lean-to extensions to suit your preference.

✓ An orangery usually possess a flat roof at the edges with a glazed lantern section right at the centre. You can also find more luxurious orangeries having two or more lantern sections. However, when it comes to the roofing, conservatories generally have more options. Some are gabled or pitched, others are lean-to with a plethora of choice to finish off the roof.

What finish is best on a wooden conservatory?

When people talk about finishes on a wooden conservatory, there are a few different things that they may be referring to. Some may be referring to the colour and type of wood used to build the conservatory, but they may also be talking about the type of treatment used to protect the wood from the weather. We’ll cover both bases for what finish is best on a wooden conservatory here.

When you’re thinking about the best wood type and finish for the conservatory, it’s best to go with a hardwood. There are both hardwoods and softwoods, and hardwoods are the most durable. Oak is the most expensive choice but is also the most durable, so lots of people decide to go for this option. Other good choices that are slightly cheaper are Brazilian cedar and idigbo. Softwoods like European redwood or Siberian larch are cheaper still, but they won’t last as long, so it may work out more cost-effective to spend more on a hardwood.

Wood is a natural material, so it’s important to look after your wooden conservatory to prevent it from rotting or getting attacked by bugs and pests. Your conservatory will be exposed to all weathers, so you’ll need to use a good finish to ensure that it stays in tip-top condition for years to come. Your installer should be able to tell you what’s best, but some of the best finishes for a wooden conservatory include breathable varnishes and decking oil. However, if you do use an oil, it’s best to use a preservative treatment too; oil will only repel water. Joints are particularly susceptible to water penetration, so make sure you use a good wood treatment and focus on areas where water would pool during rain. Then you can apply a decking oil afterwards.

do you need foundations for a lean to conservatory?

The short and simple answer to this question is yes, just like other new extensions, you must have a foundation done for your lean to conservatory. In order to transfer the building’s weight to the floor safely, there’s a need to construct a foundation. Without it, the structural integrity of the extension would be heavily compromised. What’s more? While there’s no minimum depth requirement for a lean to conservatory, there are multiple factors that can affect the depth as well as type of the foundation. Let’s take a look!

 

  • The nearby trees. What trees do is to absorb water from the soil which can affect the foundation significantly. When water is absorbed from the soil, the soil shrinks which affects the foundation’s strength. The size as well as type of the tree will determine the extent of the water absorption from the ground.
  • The soil’s suitability. The weight that each soil can withstand varies and even more so, when environmental factors have more effect on certain types of soils than others. For instance, chalk is able to drain water away relatively easily which means that nearby trees will only have a little effect on its quality. Clay, on the other hand, shrinks when drying and also retains a lot of water. This means that nearby trees will have huge impact on clay soil which will compromise the structural integrity of the lean to conservatory. Therefore, since changes to clay mostly occur to about 0.75m depth, foundations on the soil should be constructed deeper to compensate.
  • Undisturbed ground. Before the foundations are laid, there’s a need to identify grounds that hasn’t been built on and this usually takes a depth of about 1m (this figure may vary especially in regions where drains have been laid).

How to maintain your aluminium conservatory?

Aluminium conservatories are really easy to maintain, making them a top choice for many homeowners. Unlike wooden conservatories, they don’t need regular treatment to ensure they don’t deteriorate.

The most you’ll need to do to keep your aluminium conservatory looking great is give the frames and glass an odd wipe with water and a mild detergent to get rid of any occasional dirt.
