Yes, it is often possible to replace an undermount sink without removing the countertop, but success can depend on the countertop material. For materials like granite, the process is relatively straightforward. However, laminate or uniquely shaped countertops might need to be removed or modified.

The process typically involves shutting off the water supply, disconnecting the drain and plumbing pipes, cutting through the old silicone seal, and carefully lowering the sink from below. This requires a good understanding of plumbing and the right tools. If you are not confident in performing the replacement yourself, it is recommended to hire a countertop specialist or a plumber to handle the task.

The frequency for sealing granite countertops depends on several factors, including the type of sealant used, the color of the granite, and how heavily the countertops are used. As a general guideline, resealing is often recommended every 12 to 18 months, but some sources suggest it could be as often as every few months or at least once a year.

The type of sealant is a major factor: water-based sealants may need reapplication every six months to a year, while more durable solvent-based sealants can last for five to 10 years. Additionally, factors like heavy kitchen traffic, frequent use of acidic cleaners, and lighter granite colors may require more frequent sealing to prevent staining.

To determine if your countertops need resealing, you can perform a simple water test. Place a few drops of water or a wet paper towel on an inconspicuous area of the granite. After 10 to 15 minutes, check the spot. If the water has beaded up, the seal is still intact. If the water has been absorbed and darkened the stone, it's time to apply a new coat of sealant. You can choose to seal the granite yourself or hire a professional to ensure it's done correctly.

It is not recommended to put a hot pan directly on a marble countertop. While marble is heat-resistant, it is not completely heat-proof, and extreme or prolonged exposure to high heat can cause discoloration, cracking, or chipping. Pans may also scratch or nick the surface. To protect your countertop and maintain its integrity, always use trivets or hot pads. Note that faux marble finishes do not resist heat and require protection from hot items at all times.

Undermount sinks have clips that attach to the countertop, but they have pros and cons. They are heavier than drop-in sinks, so they only work with sturdy countertops like natural stone and are a more expensive option. You might need someone to help you install the sink, depending on its weight.
