Fantastic service from Raanan The Locksmith. I had them install a new deadbolt on my front door, and the technician did an outstanding job. Very fast and efficient and they handled the installation with pinpoint precision. It was worth every penny for the peace of mind.

The owner of this business installed the locks himself, and I was shocked how quick and professionally he had done it. He's coming back later next week to install a plate as well because the contractor who originally did my door did it poorly. Great work, communication, and professionalism.

Installation went great and the product is great, but price is something I will not pay again. I know the quality of the product and installation is very hhgh, but I do not think I will have other doors in house replaced soley because of cost. $5400 for one door with new frame is just too high....

Doorbell Installation questions, answered by experts

Three signs that you need crawl space insulation are drafts, high energy bills, and mold. Drafts can start in crawl spaces and cause hot or cold air to spread to the rest of your home through holes in the floors and walls. And even if your entire home is well-insulated, you can still feel an unchecked draft from your crawl space and in your utility bill. Uninsulated crawl spaces can let in air and moisture, and because they’re built directly on the ground and difficult to dry out, they are hotspots for mold and mildew.

Radiant barriers and insulation serve different purposes, so one is not inherently better than the other. Radiant barriers reflect radiant heat, helping keep spaces cool, especially in hot climates, while insulation slows heat transfer through conduction. For optimal energy efficiency, it’s best to use both together.

Radiant barriers can enhance the performance of insulation by preventing heat gain in the summer and heat loss in the winter. The choice between them depends on specific climate conditions and the building’s design requirements.

Periodic checks for moisture or pest issues ensure consistent performance.

Doubling the insulation in your home also doubles the R-value of said insulation. In other words, by adding more insulation, you can reduce the heat loss by half. Most homes benefit from increasing insulation. Older homes, in particular tend to have less insulation as is, so doubling your insulation could drastically reduce your energy bills, keep your home more comfortable, and take the strain off your HVAC system.

It is possible to install a radiant barrier yourself. However, knowing how to install a radiant barrier and actually doing it are two totally different things. For example, it’s important that they be installed in a straight line but at an angle that creates a gap between the roof panels and the foil or spray. If this gap is too large or small, it won’t function as it should, and that may be hard to avoid if you’re only a novice. When in doubt, leave this job to a pro.
