Is Sealing Block Paving Worth It in the Long Run?

Block paving is a popular choice for driveways and patios across the UK thanks to its aesthetic appeal, versatility, and durability. However, to keep it looking its best and performing well over time, many homeowners consider whether sealing is a worthwhile investment. At Newport Pagnell Driveways & Patios, we regularly advise customers in Newport Pagnell, Buckinghamshire on the pros and cons of sealing block paving—and whether it’s truly worth it in the long term.

Here’s what you need to know when making an informed decision about sealing your block paving.

What Is Block Paving Sealant?

Block paving sealant is a protective coating applied over the surface of the blocks and the jointing sand. It can be water-based or solvent-based and comes in various finishes such as matt, satin, or gloss. The sealant acts as a barrier against water, oil, dirt, weeds, and UV damage, while also enhancing the colour and finish of the paving.

Benefits of Sealing Block Paving

1. Enhanced Appearance

Sealing your paving enhances its natural colours and gives the surface a fresher, cleaner look. It can make aged or weathered paving look like new, while also preventing the fading caused by prolonged exposure to sunlight.

2. Weed and Moss Prevention

Weeds and moss can grow in the joints between blocks where moisture and organic debris accumulate. Sealing helps bind the sand in the joints, making it more difficult for weeds to take root and grow.

3. Protection Against Stains

Oil, grease, and other stains from vehicles or barbecues can permanently mark unsealed block paving. Sealant creates a non-porous surface that repels these substances, making spills easier to clean before they cause lasting damage.

4. Reduces Erosion of Jointing Sand

Jointing sand is essential to maintaining the stability of the paving blocks. Over time, this sand can be eroded by rain, wind, and pressure washing. Sealant helps lock the sand in place and reduces the need for frequent top-ups.

5. Increased Lifespan

By protecting the surface from the elements, foot traffic, and contaminants, sealing helps preserve the integrity of the paving and can significantly extend its lifespan. This leads to lower maintenance costs and fewer repairs over time.

Potential Drawbacks to Consider

While there are clear advantages, sealing block paving does come with considerations:

• Initial Cost: Applying sealant involves an upfront investment, especially if done professionally. However, this cost is often offset by reduced maintenance and repairs in the future.
  
• Regular Resealing Required: Sealant typically needs to be reapplied every 3–5 years to maintain its protective properties, depending on weather exposure and traffic levels.
  
• Incorrect Application Risks: Applying sealant to a dirty or damp surface can trap moisture and lead to a patchy or hazy finish. That’s why professional preparation and application are crucial.
  

At Newport Pagnell Driveways & Patios, we ensure that all sealing work is carried out using the appropriate products, correct techniques, and only after thorough cleaning and surface preparation.

When Is the Best Time to Seal?

Sealing should only be done in dry conditions, ideally between spring and early autumn. The surface must be completely clean and free from moss, weeds, and efflorescence (the white, powdery residue that can appear on block paving). The blocks must also be fully dry, which can take 2–3 days after cleaning, depending on the weather.

Professional assessment is important to determine if your block paving is ready for sealing, especially if it’s a new installation or hasn’t been sealed before.

Is It Worth It in the Long Run?

For most homeowners, sealing block paving is a smart investment that pays off over time. It not only improves the appearance of your driveway or patio but also protects against common problems that lead to deterioration. While the initial cost and need for maintenance should be factored in, the long-term savings and reduced hassle often make sealing well worth the effort.
