Are you environmentally friendly?

Yes we are. That’s why we use only environmentally sensitive products in all our cleaning and sealing processes. Our aim is to help keep the planet healthy.

Can I save some money by sealing my deck or walkway without cleaning it?

No, if the surface is not cleaned and prepared properly, it will look terrible once sealed and the sealing product will fail prematurely. To work properly, all sealing products need to be applied to a clean, properly prepared surface, in order to achieve maximum penetration and adhesion. When there is a layer of dirt on the surface, it creates a barrier between the sealing product and your structure, leading to pealing, flaking, and premature failure. We do the job right, which is why we strongly advise full service to help ensure your satisfaction upon job completion.

Can you remove stains from my concrete or natural stone?

Yes, with our power-washing process we can remove most rust and other stains from interlock, concrete and natural stone surfaces. We have a number of cleaners and techniques we employ to remove stains and bring the construction material back to its original state.

Do I have to be home while the work is being done?

Generally the answer is no, unless extenuating circumstances restrict access to the area being worked on. As long as we have access to water, electricity, and the job site there is no need for you to be home, though it is always nice to see the smile on your face when we are finished!

Does it really matter which concrete or natural stone sealer is used?

Yes. We use only proven quality sealers / stains that we know offer proper protection. We ensure that the sealer is suited to the material it will be used on. Protection, durability, and safety are all considerations in choosing a sealer / stain, which is why we’ve put so much effort into finding the best ones for you.

How do I stop my wooden deck or fence from turning grey?

Greying of wood is caused by exposure to Ultraviolet (UV) rays from the sun. The same UV rays that cause damage to human skin, cause the degradation of wood fibres, resulting in the breakdown of the structure. One of the early signs of this breakdown is the greying of the surface of the wood. Coating the wood with a UV blocking sealer / stain is the only way to prevent the harmful actions of the sun. We use UV protective sealers in order to ensure the protection of your wooden structures.

How long must I stay off the finished surface?

Stone and pattern concrete: Rain safe 30 minutes, walk safe 4 hours, vehicle traffic 24-48 hours

Decks: Foot traffic within 24 hours, furniture replacement 48 hours

Actual dry times may vary based on current temperatures and sun exposure

How often do I have to reseal?

Duration between cleaning and sealing depends on a number of factors as well as personal preference. Environmental factors, such as exposure to sun, moisture, over hanging trees, and exposure to salt will have a major influence. Other factors such as use, pets, children, and cleaning tendencies will also have an impact. At the end of the day there is no perfect answer though every 2-3 years is common practice with some people choosing to reseal sooner and others waiting a little longer.

When should I seal my wooden deck or fence?

Many people leave their wooden decks or fences unprotected until greying becomes quite obvious but the sun and other weather conditions start to work right away – a lot of irreversible damage is done to your wooden structure within the first year. The best time to apply a sealer / stain is as soon as construction is complete. Only then can you ensure that damage from the sun and other weather conditions is minimized. Every 2nd or 3rd season the deck or fence should be inspected by a professional to evaluate the condition of the sealer and determine if resealing is necessary. Keep in mind that horizontal surfaces like deck tops, will wear down faster than vertical surfaces like fencing. High traffic areas are especially prone to accelerated wearing of protective sealers.

Why should I seal pressure-treated wood?

Pressure-treating wood adds copper sulphates, arsenic and other chemicals to wood, in order to keep away termites and to help reduce the likelihood of the wood rotting. There is no UV or other weather protection in the pressure-treating process – the pressure-treated wood is just as susceptible to the damaging effects of the sun and weather as raw wood. Only by applying a UV protecting sealer / stain, such as those we use, can your pressure-treated wood structures be protected from the sun and other damaging weather elements. The additives in pressure treated wood are often a skin irritant – especially for children and people with respiratory problems. Sealing pressure treated wood ensures that the additives are sealed in so that they cannot irritate people, especially small children, and pets.

Will my stone or concrete walkway become slippery after it is sealed?

For smooth, non-porous concrete, we offer a special slip-resistant sealer that will help with traction. We strive to ensure that your property is both safe and beautiful when we are finished. Keep in mind all surfaces can become slippery when wet or icy.
