How To Change Kitchen Countertops: Simple Guide

What is the process for changing kitchen countertops? The process for changing kitchen countertops involves several key steps: first, planning and selecting new materials; second, safely removing the old counters; third, preparing the base cabinets; and finally, installing the new surface, followed by sealing and finishing touches. This guide will walk you through each part of the kitchen countertop replacement journey, making your DIY countertop installation achievable.

Planning Your Kitchen Countertop Overhaul

Before lifting a single tool, planning is the most crucial stage. Good planning saves time, money, and frustration later on.

Selecting the Right Countertop Materials

Choosing the best countertops for kitchen renovation depends on your budget, lifestyle, and aesthetic goals. A countertop materials comparison is essential here.

Material Pros Cons Average Cost (per sq. ft., installed)
Laminate Cheap, many styles, easy install Scratches easily, not heat resistant \$25 – \$75
Butcher Block Warm look, repairable, DIY friendly Needs regular sealing, susceptible to water damage \$45 – \$150
Quartz Very durable, low maintenance, non-porous Higher initial cost, can chip if hit hard \$75 – \$160
Granite Very durable, unique patterns, heat resistant Requires periodic sealing, heavy, higher cost \$75 – \$200
Solid Surface (Acrylic) Seamless look, repairable, non-porous Scratches easily, can look less premium \$60 – \$135

If you are aiming for a budget-friendly face-lift, consider a laminate countertop upgrade. If you are ready for a major change, look into natural stone or quartz.

Budgeting for Your Project

A major factor is cost. If you are thinking about stone, you need to know the granite countertop installation cost beforehand. This cost varies based on the slab thickness, complexity of the cuts (like for sinks or cooktops), and where you live. Remember to add 10-15% extra for unexpected needs, like minor cabinet adjustments.

Measuring Accurately

Measure twice, cut once—this applies strongly to countertops. Measure the depth and length of every cabinet run. Note the location and size of any cutouts needed for sinks (undermount or drop-in) and cooktops. Always add about one inch of overhang (usually 1 to 1.5 inches) past the front of your cabinets for a finished look.

Phase One: Taking Out the Old Surface

This is often the toughest part of the job. Safe removal is key when removing old kitchen counters.

Safety First

Wear heavy gloves and safety glasses. Old countertops, especially stone or solid surfaces, are very heavy. Have at least one helper ready, even if your counters are laminate.

Disconnecting Fixtures

  1. Shut Off Water: Locate the shut-off valves under the sink. Turn the hot and cold water lines off. Turn the faucet on briefly to drain any remaining water pressure.
  2. Disconnect Plumbing: Use a basin wrench to disconnect the supply lines from the faucet. Disconnect the drain pipes from the sink basin.
  3. Electrical Safety: If you have a garbage disposal or outlets wired near the counter area, switch off the power at the main circuit breaker before doing anything else.
  4. Remove Sink and Faucet: If it is a drop-in sink, remove the clips holding it underneath. Gently lift the sink out. If it is an undermount sink, you may need to cut the adhesive seal with a utility knife before lowering it.

Detaching the Countertops

Most countertops are held down in a few ways:

  • Screws: Look underneath the cabinets. You will often see screws going up through the cabinet braces into the bottom of the countertop. Remove all these screws.
  • Adhesive/Caulk: Countertops are usually sealed to the backsplash or walls with silicone caulk. Use a sharp utility knife to carefully slice through this seal all the way around the perimeter. If the counter is glued heavily to the base cabinets (common with laminate or solid surface), you might need to gently pry upward using wooden wedges placed between the cabinet frame and the counter underside. Use light, steady pressure.

Once all fasteners and seals are broken, carefully lift the old sections. If they are large or heavy (like stone), move them away slowly with assistance.

Phase Two: Preparing the Cabinets

New countertops need a perfect, level foundation. Damaged or sagging cabinets will ruin the look and function of your new surface.

Repairing and Reinforcing Cabinetry

Examine the top edges of your base cabinets after the old tops are gone.

  • Check for Water Damage: Look for mold or soft, rotting wood, especially near sink areas. Cut out any damaged sections and replace them with new plywood or solid lumber pieces, secured with screws and strong wood glue.
  • Leveling: Cabinets must be level and plumb. Use a long level across the tops of the cabinets. If a cabinet section dips, you can shim it using thin pieces of wood or specialized leveling shims placed between the cabinet base and the floor, or between the cabinet top support and the cabinet itself. Adjust until everything is flat and even.

Adding Support for Heavier Materials

If you are installing stone (granite or quartz), extra support is often needed, even if the manufacturer doesn’t strictly require it. This adds peace of mind against sagging or cracking over time.

  • Install support strips (often 1×3 lumber) screwed firmly along the top edges of the front and back rails of the cabinets. This creates a solid platform for the stone to rest on.

Phase Three: Installing Your New Countertops

The installation method changes based on the material chosen.

Installing Laminate or Solid Surface Counters

These materials are lighter and more forgiving for DIY work.

  1. Dry Fit: Place the new countertop sections into position without glue or screws first. Check the seams where two pieces meet. Ensure the overhang looks correct on all sides. Mark any required sink or cooktop cutouts onto the top surface lightly with a pencil.
  2. Making Cutouts: For laminate, use a circular saw with a fine-tooth, non-scratching blade (or a laminate-specific blade). Cut on the underside of the counter, cutting slightly outside your pencil lines. Finish the cut near the edges with a jigsaw. After cutting, you must seal the raw edges (the particleboard core) with waterproof sealant or contact cement to stop moisture absorption.
  3. Securing: Apply a bead of construction adhesive (like Liquid Nails) to the top support edges of the cabinets. Gently set the new top down. Secure it from below with screws, making sure the screws are not too long—they should not poke through the top surface!

If you are following a butcher block countertop tutorial, installation is similar, but you may use specialized metal brackets or elongated screws that allow the wood to expand and contract naturally with humidity changes.

Installing Stone or Quartz (Professional Consideration)

While the removal part is DIY-friendly, installing heavy slab materials like granite is often best left to professionals. However, if you are attempting it yourself:

  • Fabrication is Key: Stone slabs must be precisely cut to size, have sink cutouts routed, and edges polished before they arrive at your home. This requires specialized, diamond-tipped tools.
  • Lifting: Stone requires significant manpower or specialized suction-cup lifting tools. Set the slab slowly onto the cabinets.
  • Adhesion: Use 100% silicone caulk or epoxy specifically designed for stone countertops to adhere the slab to the cabinets.
  • Seaming: If you have multiple pieces, the seams must be perfectly aligned and filled with an epoxy resin color-matched to the stone. This step requires skill to achieve an almost invisible line.

Phase Four: Finishing Touches and Sealing

Once the main surface is down, the final details make the kitchen functional and beautiful.

Installing the Sink and Faucet

If you removed an old sink, clean the cabinet area thoroughly.

  1. Undermount Sinks: Apply a heavy bead of 100% silicone sealant around the rim of the sink basin. Carefully lift the sink into place against the underside of the counter. Secure it tightly using the mounting clips provided. Wipe away excess silicone immediately.
  2. Drop-in Sinks: Place a bead of silicone around the lip of the sink. Set the sink into the cutout and secure it from below with mounting hardware.
  3. Plumbing Reconnection: Reconnect the drain assembly and water supply lines. Turn the water back on slowly and check carefully for leaks under the sink for several hours.

Backsplash and Edge Sealing

If your old backsplash was attached to the old countertop, you will likely need new material or a transition piece.

  • Caulking: Run a thin, neat bead of silicone caulk wherever the new countertop meets the wall backsplash or tile. This seals out moisture and prevents grime buildup. Use painter’s tape on both surfaces to ensure a perfectly straight caulk line.

Sealing New Countertops

Different materials require different care. Sealing new countertops is vital for longevity, especially with porous materials.

  • Granite and Marble: These stones are porous and absorb liquids, leading to stains. Most granite requires sealing upon installation and then perhaps once a year. Use a high-quality impregnating sealer, following the manufacturer’s instructions for application and cure time.
  • Butcher Block: This material needs regular oiling or sealing. For food prep areas, mineral oil is common. For general use, a durable polyurethane or tung oil finish offers better water resistance. You may need to apply several coats initially.
  • Quartz and Laminate: These are generally non-porous and do not require sealing. Maintenance is usually just wiping clean.

Deciphering Alternatives: Refinishing vs. Replacing

Sometimes, a full replacement isn’t necessary or affordable.

Considering Refinishing Old Countertops

Refinishing old countertops can be a viable, low-cost alternative, especially if your existing counters are solid wood or laminate that has minor surface damage.

  • Laminate Refinishing: Specialized countertop refinishing kits use epoxy paint designed to bond strongly to laminate surfaces. This process involves heavy sanding, cleaning, priming, and applying multiple coats of the epoxy finish. While cheaper than replacement, the durability is less than new material, and chipping can occur over time.
  • Solid Surface/Laminate Repair: Small chips or burns in solid surfaces (like Corian) can often be patched and sanded smooth by a professional, making them look new again.

When Replacement is the Only Option

If your existing laminate countertops are heavily water damaged (the core particleboard is swollen or disintegrating), or if the surface is severely chipped, stained, or cracked beyond repair, then full kitchen countertop replacement is the only path to a lasting solution.

Project Management Tips for DIY Installation

To keep your project running smoothly, use these organizational tips:

  • Staging Area: Designate a space outside the kitchen (garage or dining room) for laying out tools, reading manuals, and temporarily placing hardware.
  • Tool Rental: Heavy tools needed for stone cutting or specific plumbing disassembly (like basin wrenches) are often best rented for a single day rather than purchased.
  • Order Timeline: If using custom-cut materials (stone, quartz), confirm the lead time. This can range from two weeks to two months. Plan your demolition date after the new materials have arrived and been inspected.
  • Cabinet Access: Ensure you have clear, safe access to the space beneath the cabinets for securing fasteners and connecting plumbing.

Fathoming Material Depth: Butcher Block Specifics

The butcher block countertop tutorial experience is unique because the wood breathes.

Butcher Block Installation Steps:

  1. Acclimation: Let the wood sit in the kitchen area for several days to adjust to the local humidity.
  2. Template Creation: Use thin plywood or cardboard to make a perfect template of your cabinet layout, including cutouts. Transfer this template to the butcher block, remembering to add the desired overhang (usually 1.5 inches on the front, 0.5 inches on the sides).
  3. Cutting: Use a good quality saw. Always cut the longest sides first.
  4. Finishing: Apply your chosen sealant (oil or varnish) to all six sides of the countertop—top, bottom, and all four edges—before installation. This prevents moisture imbalance that leads to warping.
  5. Attachment: Attach using metal mounting clips designed for wood, or use screws driven through slotted holes in the cabinet support strips. Slotted holes allow the wood to expand without buckling the countertop or breaking the screws.

Final Checklist for a Successful Upgrade

Completing your countertop change involves one last review.

  • Are all sink and faucet connections leak-free?
  • Is the overhang even on all visible sides?
  • Has the seam (if applicable) been properly filled and cured?
  • Is the perimeter caulked against the wall?
  • Have you applied the required sealant to porous materials?

A beautiful new kitchen surface elevates the entire room. By tackling removing old kitchen counters and carefully installing the new material, you can achieve a professional look through dedicated DIY countertop installation.

Frequently Asked Questions (FAQ)

Q: Can I install heavy granite countertops myself?
A: While possible, installing heavy granite requires specialized lifting equipment, precise cutting (fabrication), and seam-joining skills that most DIYers lack. It is often recommended to hire professionals for the installation part, even if you handle the demolition.

Q: How long does it take to refinish old countertops?
A: Refinishing usually takes about 3 to 5 days, but much of that time is waiting for coats to cure. Active work time might only be 8 to 12 hours spread over those days.

Q: What is the cheapest way to update my look?
A: The cheapest methods involve either refinishing old countertops with an epoxy kit or opting for a laminate countertop upgrade using a modern pattern, as laminate is the least expensive material per square foot.

Q: Do I have to remove the sink before taking off the old counter?
A: Yes, absolutely. You must disconnect the plumbing, remove the sink basin itself, and disconnect the faucet connections before attempting to loosen the countertop, as the weight of the sink basin alone can cause the counter to break or fall when lifted.

Q: Are butcher block countertops hard to maintain?
A: They require more maintenance than stone or quartz. They must be oiled or sealed regularly (monthly for oil, annually for varnish) to protect them from water rings and stains, but they are easy to repair if scratched deeply.
