Should You Install New Siding Over Old?

Can you install new siding without removing the old siding?

Short answer: Yes. But let’s review the pros and cons:

Installing new siding over existing siding can save you money by eliminating the need to remove the old siding, which can be time-consuming and more expensive due to removal and disposal fees. The old siding also adds an extra layer of insulation, which can help to improve your home’s energy efficiency and reduce heating and cooling costs. And installing new siding over the old can avoid the risk of potentially damaging the underlying structure. 

However, installing new siding over old siding can sometimes create an unappealing finished look. The new siding may not fit as snugly, leading to bulges or bumps in the surface. And when you install new siding over old siding, you are essentially trapping the old siding between two layers of material. Doing so can create a moisture trap that can lead to the growth of mold and mildew, reducing the lifespan of both layers of siding. Finally, adding a layer of new siding on top of the old can sometimes cause issues with your windows, doors, and trim. The added thickness can make it difficult to properly install these items, which can lead to gaps and leaks.

Overall, while installing new siding over old siding can save you time and money, it may not be the best choice in all situations. It's important to consider the potential drawbacks and consult with a professional like Retex to determine the best course of action for your specific situation.
