Quartz countertops have become a popular choice for contemporary kitchens and bathrooms due to their durability, low maintenance, and stylish appearance. However, like all countertop materials, quartz does wear over time and may eventually need replacing. This leads many homeowners to wonder: can I replace my quartz countertop without damaging the existing cabinets?

What to Consider Before Replacing Quartz Countertops

When preparing for a quartz countertop replacement, there are a few key factors to keep in mind:

Assess the Condition of Existing Cabinets

Take a close look at the current condition of your cabinets. Are doors and frames structurally sound? Is the finish worn or damaged? Address any issues with the cabinet box, doors, or hardware before installing new countertops. Reinforce as needed to support new weight.

Choose an Experienced Installer

Quartz countertop installation is a specialized skill – don’t attempt a DIY replacement. Hire a professional installer experienced in removing and replacing quartz. They have the skills to remove the countertop without damaging cabinets.

Understand the Original Installation Method

Knowing details like the type of adhesive used, reinforcement with brackets or screws, and if the counter was undermounted or top mounted will help guide the replacement process. Ask the original installer or inspect underneath.

Plan Ahead to Minimize Disruption

A countertop replacement often requires disconnecting plumbing, removing backsplashes, and clearing countertops. Plan where appliances and kitchen items will be stored safely during the replacement to reduce stress.

Can Cabinets Be Damaged During Quartz Countertop Replacement?

Quartz countertops are heavy – a full slab can weigh over 100 pounds per square foot. Improper removal techniques can damage cabinets and cause:

Loosening of joints and frames
Cracking or chipping of cabinet surfaces
Lifting of laminate finishes
Stripping of screw holes

However, with proper precautions and an experienced installer, quartz countertops can be replaced without damaging cabinets. Here are key steps installers take to protect cabinets during removal:

1. Inspect and Prep the Cabinets

The installer will examine cabinets for any potential issues and reinforce as needed. They may:

Resecure loose joints or frames
Add corner brackets for extra support
Repair damaged surfaces and finishes

Proper prep helps cabinets withstand the installation process.

2. Disconnect and Remove Appliances

Appliances like sinks, stovetops, and cooktops will be disconnected and removed prior to taking out the countertop. This prevents damage from trying to maneuver appliances still attached to countertops.

3. Lift Off Countertops Carefully

Installers avoid prying quartz slabs loose, which can crack seams and damage cabinets. They may heat the adhesive to loosen the bond and then carefully lift slabs up and off without force.

4. Remove Adhesive Residue

Adhesive will be thoroughly removed from cabinets using scrapers, heat, and cleaning solutions. This prevents uneven surfaces that could compromise new countertop installation.

5. Inspect and Repair Cabinets

Once countertops are removed, cabinets will be inspected again and any necessary repairs made prior to installing the new quartz. Holes will be patched, surfaces sanded and cleaned, and reinforcements added.

Protecting Cabinets During New Quartz Installation

Installers also take precautions during the installation of new quartz countertops to avoid damaging cabinets:

Clamps and shims – These are used to evenly support countertops during installation without putting excess strain on cabinets.
Cushioned supports – Foam, rubber, or cork pads placed on cabinets provide a buffer as quartz slabs are positioned.
Even tightening – New countertops are fastened gradually with corner clamps to ensure uniform pressure.
Surface protection – Cabinets are shielded from adhesive drips and scratches using painters tape, drop cloths, or plastic sheeting.

Signs of Cabinets Damaged By Quartz Installation

Unfortunately, cabinet damage can still occur if proper precautions aren’t taken during removal and replacement. Here are signs to look out for:

Uneven countertops – If new quartz slabs rock or are uneven, the underlying cabinet structure may have been compromised.
Separated joints – Gaps or seams opening up where cabinets meet could indicate damage.
Popped screws – Check for screws pulling loose at corners or along frames.
Cracked surfaces – Inspect for any new cracks, chips, or gouges on cabinet surfaces.
Lifting laminate – Watch for peeling or lifted corners of cabinet laminate finishes.

Repairing Cabinet Damage from Quartz Installation

If cabinets do sustain damage during the quartz replacement process, the issues can be fixed:

Reinforce frames – Add new corner brackets, braces, or L-brackets to reinforce weakened joints.
Refasten surfaces – For laminate peeling, resecure with waterproof wood glue and use iron to reactivate bonding.
Fill cracks – Repair chips and cracks with wood filler then sand and restain for an even finish.
Replace damaged doors – Severely damaged doors may need complete replacement.
Conceal cosmetic flaws – For minor cosmetic damage, apply wood putty then repaint or restain.

While cabins can be repaired, preventing damage in the first place is ideal. Hiring experienced quartz installers reduces the risks.

Choosing Experts to Replace Your Quartz Countertops

To safely remove and replace quartz countertops without damaging your cabinets, homeowners should look for these traits when hiring installers:

Quartz certification – Many reputable fabricators have installers specially trained and certified in working with quartz.
5+ years experience – Look for an established company with ample experience replacing quartz countertops.

Cabinetry expertise – Opt for installers used to working around cabinetry without damage.

Replacing quartz provides the chance to refresh the look of your kitchen or bath with a brand new countertop. Investing in professional installers experienced in quartz replacement will help ensure your existing cabinets come through the process undamaged. With proper care and precautions taken by installers, it is possible to replace quartz countertops without damaging cabinets.

Frequently Asked Questions About Replacing Quartz Countertops

Replacing quartz countertops in your kitchen or bathroom brings up many questions for homeowners. Here are answers to some of the most common FAQs:

Can I replace just a section of my quartz countertop?

While it is possible to replace only a portion, the seam between new and existing quartz is often quite visible. The cost of fabricating a small section is generally comparable to replacing the entire top. For best appearance, a full replacement is recommended.

What risks are there to DIY quartz countertop replacement?

Attempting to remove and install quartz without experience risks damaging cabinets, incorrectly installing the new top, personal injuries, and voiding warranties. The specialized tools, knowledge of fabrication techniques, and moving heavy slabs make DIY replacement inadvisable.

How long does it take to replace quartz countertops?

The complete process often takes 2-3 days. Day 1 involves prep work like clearing countertops and disconnecting sinks. Day 2 is removing the old top and installing the new one. Day 3 allows adhesives to fully cure before reconnecting appliances.

Can new quartz countertops go over my old ones?

Directly installing over existing quartz is not recommended. The combined thickness may not fit properly over cabinetry. It’s best to completely remove old quartz prior to measuring for new countertops.

Should I replace backsplash when I replace quartz countertops?

Most experts recommend installing all new quartz and backsplash together for the best finished appearance. This allows you to match colors and patterns properly. Removing just a backsplash also risks cabinet damage.

How much does it cost to replace quartz countertops?

The average cost ranges from $2,500 to $5,000 depending on the size of the kitchen, slab colors and patterns chosen, and local labor rates. Complex installations or high-end quartz can increase costs.

What maintenance helps quartz counters last longer?

Use cutting boards to avoid direct cuts on the surface
Wipe up spills quickly to prevent staining
Clean with a PH-neutral stone cleaner
Avoid harsh chemicals and abrasive cleaners
Reseal with a penetrating sealer every 1-2 years

Conclusion

Replacing worn or outdated quartz countertops provides the opportunity to give your kitchen or bath a fresh new look. With proper planning, hiring experienced installers, and taking precautions during the installation process, it is possible to remove and replace quartz countertops without damaging existing cabinetry. Protecting cabinets with reinforcements, cushions, and drop cloths allows for safe removal. Clamps, shims, and gradual tightening techniques prevent cabinet damage when installing the new tops. While accidents can still occur, choosing professional quartz installers with cabinetry expertise minimizes risks. With care and patience taken by installers, your cabinets can come through the quartz replacement process unscathed.
